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 > systemd[1]: Starting Elasticsearch... > -- Subject: Unit elasticsearch.service has begun start-up > -- Defined-By: systemd > -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel > -- > -- Unit elasticsearch.service has begun starting up. > ... systemd-entrypoint[1852]: Exception in thread "main" java.lang.RuntimeException: starting java failed with [1] > ... systemd-entrypoint[1852]: output: > ... systemd-entrypoint[1852]: error: > ... systemd-entrypoint[1852]: OpenJDK 64-Bit Server VM warning: Ignoring option UseConcMarkSweepGC; support was removed in 14.0 > ... systemd-entrypoint[1852]: OpenJDK 64-Bit Server VM warning: Ignoring option CMSInitiatingOccupancyFraction; support was removed in 14.0 > ... systemd-entrypoint[1852]: OpenJDK 64-Bit Server VM warning: Ignoring option UseCMSInitiatingOccupancyOnly; support was removed in 14.0 > ... systemd-entrypoint[1852]: Unrecognized VM option 'PrintGCDateStamps' > ... systemd-entrypoint[1852]: Error: Could not create the Java Virtual Machine. > ... systemd-entrypoint[1852]: Error: A fatal exception has occurred.

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 -Xss1m -Djava.awt.headless=true -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 #-XX:+PrintGCApplicationStoppedTime -Xloggc:/var/log/elasticsearch/gc.log #-XX:+UseGCLogFileRotation #-XX:NumberOfGCLogFiles=8 #-XX:GCLogFileSize=64m ---
