Hi, I'm trying to run elasticsearch (fresh install) on Deepin 15.3 but it seems it stuck. Here is the error log: Exception in thread "main" java.lang.NoClassDefFoundError: org/elasticsearch/common/jackson/dataformat/yaml/snakeyaml/error/YAMLException at org.elasticsearch.common.jackson.dataformat.yaml.YAMLFactory.\_createParser(YAMLFactory.java:426) at org.elasticsearch.common.jackson.dataformat.yaml.YAMLFactory.createParser(YAMLFactory.java:327) at org.elasticsearch.common.xcontent.yaml.YamlXContent.createParser(YamlXContent.java:90) at org.elasticsearch.common.settings.loader.XContentSettingsLoader.load(XContentSettingsLoader.java:45) at org.elasticsearch.common.settings.loader.YamlSettingsLoader.load(YamlSettingsLoader.java:46) at org.elasticsearch.common.settings.ImmutableSettings$Builder.loadFromStream(ImmutableSettings.java:982) at org.elasticsearch.common.settings.ImmutableSettings$Builder.loadFromUrl(ImmutableSettings.java:969) at org.elasticsearch.node.internal.InternalSettingsPreparer.prepareSettings(InternalSettingsPreparer.java:110) at org.elasticsearch.bootstrap.Bootstrap.initialSettings(Bootstrap.java:144) at org.elasticsearch.bootstrap.Bootstrap.main(Bootstrap.java:215) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:32) Caused by: java.lang.ClassNotFoundException: org.elasticsearch.common.jackson.dataformat.yaml.snakeyaml.error.YAMLException at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 11 more I'm using "/usr/lib/jvm/java-8-openjdk-amd64/", and when I run: java -verbose:class -cp elasticsearch-1.7.6.jar:lucene-core-4.10.4.jar org.elasticsearch.Version the result is: Error: Could not find or load main class org.elasticsearch.Version I have read other similar topics which seems like old problems (2014-2016) and tried several solutions but to no avail. Is there any working solution for this problem on Deepin 15.3? ---

Hey very welcome in the community. At first the statement, that everything in your version is way unsupported or old like: Elasticsearch 1.7.6 [https://www.elastic.co/support/eol](https://www.elastic.co/support/eol) Deepin 15.3 - this OS in general is not support officially [https://www.elastic.co/de/support/matrix](https://www.elastic.co/de/support/matrix) I understand that you downloaded Elasticsearch 1.7.6 [http://www.elastic.co/downloads/past-releases/elasticsearch-1.7.6](http://www.elastic.co/downloads/past-releases/elasticsearch-1.7.6) So first - why do you want to install such old version? Apart from that I did test your version call: ```auto java -verbose:class -cp elasticsearch-1.7.6.jar:lucene-core-4.10.4.jar org.elasticsearch.Version ``` The error ```auto Error: Could not find or load main class org.elasticsearch.Version ``` happens when you aren't in the correct library path where the jar files are located, so please change there at first, assuming you installed the deb package: ```auto cd /usr/share/elasticsearch/lib ``` If you've downloaded the tar.gz just go to the lib directory. Please still give a bit detail how you started elasticsearch. In case you installed the deb package you can start it by /etc/init.d/elasticsearch start and under /var/log/elasticsearch/elasticsearch.log you will find the logfile. At the moment I don't where your Exception is coming from but seems that you tried to install it from wrong directory and back then default directory still was not under /etc but under installation path in directory `config`. if Elasticsearch is start you can always do a curl localhost:9200 and Elasticsearch should answer with some version information. Hope that helps. ---

Hi Andre, Thanks for pointing me out that I installed the old version.. I didn't realised it since I install the software using apt-get. After installed the version 7.1 from .deb package, I still got an exception when running the elasticsearch: I started elasticsearch by running: sudo /bin/systemctl daemon-reload sudo /bin/systemctl enable elasticsearch.service sudo systemctl start elasticsearch.service it's active when checked using: sudo /bin/systemctl status elasticsearch.service but I still cannot access it from localhost:9200, so I tried running it directly.. `febrifahmi@djamansusah:~$ /usr/share/elasticsearch/bin/elasticsearch Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp Exception in thread "main" java.nio.file.AccessDeniedException: /etc/elasticsearch/jvm.options at java.base/sun.nio.fs.UnixException.translateToIOException(UnixException.java:90) at java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:111) at java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:116) at java.base/sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:219) at java.base/java.nio.file.Files.newByteChannel(Files.java:373) at java.base/java.nio.file.Files.newByteChannel(Files.java:424) at java.base/java.nio.file.spi.FileSystemProvider.newInputStream(FileSystemProvider.java:420) at java.base/java.nio.file.Files.newInputStream(Files.java:158) at org.elasticsearch.tools.launchers.JvmOptionsParser.main(JvmOptionsParser.java:60)` and another error: `febrifahmi@djamansusah:~$ /usr/share/elasticsearch/bin/elasticsearch Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=gasp OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

You would be better off running things via the Elasticsearch user itself if you can. ---

Hi, The problem is solved after i checked the elastic.log file and uncomment the 'cluster.initial\_master\_nodes' setting. Elasticsearch is now running on my Deepin 15.3. Thanks. 🙂 Regards ---
