Hi, I'm upgrading a single node, dev instance of elasticsearch running 6.4.2 to 7.12.1 as the first step in getting ready to upgrade our prod cluster. I was able to upgrade from 6.4.2 -\> 6.8.15 without issue but on upgrading to 7.12.1, I see this error on startup: `May 18 15:36:01 ews-dev11 elasticsearch: could not find java in bundled JDK at /data/elasticsearch-sw/jdk/bin/java` But: ```auto bash-4.2# data/elasticsearch-sw/jdk/bin/java -version openjdk version "16" 2021-03-16 OpenJDK Runtime Environment AdoptOpenJDK (build 16+36) OpenJDK 64-Bit Server VM AdoptOpenJDK (build 16+36, mixed mode, sharing) ``` I did some research but wasn't able to get it to start using the bundled jdk. In my systemd startup script, I added: `Environment=ES_JAVA_HOME=/` Which makes it use the old, default java install on the box in /bin which of course results in this warning: `May 18 16:13:24 ews-dev11 elasticsearch: Future versions of Elasticsearch will require Java 11; your Java version from [/usr/local/java/jre] does not meet this requirement. Consider switching to a distribution of Elasticsearch with a bundled JDK. If you are already using a distribution with a bundled JDK, ensure the JAVA_HOME environment variable is not set.` This worked but I'd much prefer to use the bundled jdk I'm running on a centos 7 server that's fairly well locked down and I have to run everything out of the /data directory on the box. elasticsearch-sw is a symlink to a directory (elasticsearch-sw -\> /data/bin/elasticsearch-7.12.1) where I unzipped elasticsearch install. JAVA\_HOME is not set and prior to adding it, ES\_JAVA\_HOME wasn't being set in my systemd startup script. What am I missing? ---

After posting my question, I thought it might be that the user running elasticsearch might not have access to the bundled jvm so I fixed the permissions and commented out the reference to ES\_JAVA\_HOME from my startup script but now I see this set of errors: ```auto May 18 17:00:52 ews-dev11 elasticsearch: Exception in thread "main" java.lang.RuntimeException: starting java failed with [1] May 18 17:00:52 ews-dev11 elasticsearch: output: May 18 17:00:52 ews-dev11 elasticsearch: error: May 18 17:00:52 ews-dev11 elasticsearch: Unrecognized VM option 'UseConcMarkSweepGC' May 18 17:00:52 ews-dev11 elasticsearch: Error: Could not create the Java Virtual Machine.

For which this: > [@Elasticsearch won't start after 7.9.1 to 7.9.2 upgrade](https://discuss.elastic.co/t/elasticsearch-wont-start-after-7-9-1-to-7-9-2-upgrade/249878/2): > > I'm seeing the same thing on Ubuntu 18.04. A quick google of the error tells me it's related to this: Upgrades Infra/Packaging Upgrade the bundled JDK to JDK 15 [#62580](https://github.com/elastic/elasticsearch/pull/62580) UPDATE: So my automated approach of updating elasticsearch ignores any new versions of configuration files. Forcing reinstall using sudo apt install --reinstall -o Dpkg::Options::="--force-confask,confnew,confmiss" elasticsearch gave me an updated jvm.options that solves the issue. Here's the diff: # diff jvm.options jvm… appears to be the solution. ---

Is it always gonna be there? Shouldn't I just leave it unset so it will default to the bundled jvm? I think the initial problem was file permissions - I has unzipped the bits as root. I could also go with specifically setting to /data/elasticsearch-sw/jdk ---
