Elasticsearch 7.8 does not stat Java problem

aurimas · August 21, 2020, 10:11am

Hi,
I am trying to fresh install and launch Elasticsearch 7.8 on RHEL 7.8 but I am getting into some kind of Java problems. I want it to run standalone.
Tried various ways I found on internet to fix it. But none helped. Any idea whats wrong?

journalctl -xe

Seems the 'Unrecognized VM option 'PrintGCDateStamps'' is the key - find a way to not set that I guess. Seems odd the new install would include that unless you are getting the wrong version of Java, but seems to be using the V14 JVM.

Yes, I have copied config from older server at some point, and it seems that some of parameters are now comparable. I have fixed the problem by throwing away parameters one by one from jvm.options file:

-Xms2g
-Xmx2g
-Djava.io.tmpdir=/data/elk/tmp
-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly
-XX:+DisableExplicitGC
-XX:+AlwaysPreTouch
-server

-Dfile.encoding=UTF-8
-Djna.nosys=true
-Djdk.io.permissionsUseCanonicalPath=true
-Dio.netty.noUnsafe=true
-Dio.netty.noKeySetOptimization=true
-Dlog4j.shutdownHookEnabled=false
-Dlog4j2.disable.jmx=true
-Dlog4j.skipJansi=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:+PrintGCDetails
#-XX:+PrintGCDateStamps
#-XX:+PrintTenuringDistribution
