Hello folks, I have been trying to get Elastic Stack to run for at least 2 days now, I have been given a project in school that requires me to use Elasticsearch 5.2.0 specifically (Logstash 5.2.0, and Kibana 5.2.0) I have not been able to get past installing Elasticsearch yet because it always fails to run the service. I have Java8 and Java11 (using Java8 for ES 5.2.0). The service always fails to run and anytime I check the error logs I keep getting the below: ```auto [2022-11-17T20:37:58,110][INFO][o.e.p.PluginsService] [F-2-m97] loaded module [reindex] [2022-11-17T20:37:58,110][INFO][o.e.p.PluginsService] [F-2-m97] loaded module [transport-netty3] [2022-11-17T20:37:58,110][INFO][o.e.p.PluginsService] [F-2-m97] loaded module [transport-netty4] [2022-11-17T20:37:58,110][INFO][o.e.p.PluginsService] [F-2-m97] no plugins loaded [2022-11-17T20:37:58,779][ERROR][o.e.b.Bootstrap] Exception java.lang.IllegalStateException: No match found at java.util.regex.Matcher.group(Matcher.java:645) ~[?:?] at org.elasticsearch.monitor.os.OsProbe.getControlGroups(OsProbe.java:216) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.os.OsProbe.getCgroup(OsProbe.java:414) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.os.OsProbe.osStats(OsProbe.java:466) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.os.OsService.(OsService.java:45) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.MonitorService.(MonitorService.java:45) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.node.Node.(Node.java:345) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.node.Node.(Node.java:232) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Bootstrap$6.(Bootstrap.java:241) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:241) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:333) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:121) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:112) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.cli.SettingCommand.execute(SettingCommand.java:54) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.cli.Command.main(Command.java:88) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:89) [elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:82) [elasticsearch-5.2.0.jar:5.2.0] [2022-11-17T20:37:58,788][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: java.lang.IllegalStateException: No match found at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:125) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:112) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.cli.SettingCommand.execute(SettingCommand.java:54) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.cli.Command.main(Command.java:88) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:89) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:82) ~[elasticsearch-5.2.0.jar:5.2.0] Caused by: java.lang.IllegalStateException: No match found at java.util.regex.Matcher.group(Matcher.java:645) ~[?:?] at org.elasticsearch.monitor.os.OsProbe.getControlGroups(OsProbe.java:216) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.os.OsProbe.getCgroup(OsProbe.java:414) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.os.OsProbe.osStats(OsProbe.java:466) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.os.OsService.(OsService.java:45) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.monitor.MonitorService.(MonitorService.java:45) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.node.Node.(Node.java:345) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.node.Node.(Node.java:232) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Bootstrap$6.(Bootstrap.java:241) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:241) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:333) ~[elasticsearch-5.2.0.jar:5.2.0] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:121) ~[elasticsearch-5.2.0.jar:5.2.0] ... 6 more ``` I have checked almost all online resource there is, with no luck!

Hello Mark, Thank you! Here is the elasticsearch.yml file: ```auto # ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please consult the documentation for further information on configuration options: # https://www.elastic.co/guide/en/elasticsearch/reference/index.html # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # #cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # #node.name: node-1 # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # #path.data: /path/to/data # # Path to log files: # #path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 10.0.0.4 # # Set a custom port for HTTP: # #http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # #discovery.zen.ping.unicast.hosts: ["host1", "host2"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # #discovery.zen.minimum_master_nodes: 3 # # For more information, consult the zen discovery module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true ``` I really hope this can get resolved today! ---

Hello, I am using a Microsoft Azure VM running Linux Ubuntu 20.04 (ubuntu-server-focal), 16GB RAM, 2 CPUs, 128GB Hard Disk. I was told by @jasontedor on the GitHub thread ([ES doesn't start due to a problem with REGEX matching of entries in '/proc/self/cgroup' · Issue #23218 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/23218)) to upgrade to v5.2.2 to solve the issue (because of it's backward compatibility with v5.2.0), however I encounter the same exact issue on that v5.2.2 ```auto [2022-11-18T14:57:54,900][INFO][o.e.n.Node] [] initializing ...

This is taking too much of time to setup... I am using OpenJDK-8-jre as the Java runtime environment. The Ubuntu machine I am running is a fresh install and all the depencies on there are managed and installed by me. So there can be no conflicts there I assume... I have had to deploy three vm's for testing and to no luck! ---

Given that the version you are using is very old, I would recommend looking at the [support matrix](https://www.elastic.co/support/matrix) and make sure you use an operating system that is officially supported. It may work on newer versions, but I have not touched the version you are trying to use in years, so do not know. ---

Hello, apparently the problem was not with the ELK stack version, but with the OS version (see [Elastic Support Matrix](https://www.elastic.co/support/matrix). I had to downgrade from Ubuntu 20.04 to Ubuntu 16.04 because ES 5.2.\* works well on 16.04 but with some of its own bugs. Thanks for your help! ---
