![]() ![]() The default-jre is an excellent choice for most situations, thanks to the outstanding track of backwards compatibility of the Java Virtual Machine. Ubuntu offers the default-jre package, which is regularly updated to ship the latest version of the current OpenJDK JRE in Long Term Support (LTS). Moreover, the non LTS versions of Java are bringing a steady stream of innovation into the language, and also see some adoption. Nowadays, Java 11 is the current Long Term Support (LTS) version, but Java 8 is still widely used. With new versions of Java released every 6 months, there are multiple versions available for use. I raised these questions on the forum already at Overriding default jvm options is not working (elastic 7.16.2 and java 11) with no answer yet.Previous step Next step 2. Should be file name in directory /config// somehow differ from file name in root directory /config/ ?Īre there any other options how to specify the path to gc.logs instead of changing jvm.options ? Whatever worked for me in the root /config/jvm.options, doesn't work in /config//jvm.optionsĪm I missing something else in configuration ? ![]() I tried this use case: left the root /config/jvm.options unchangeable, copied it into /config//jvm.options, made the change in it but in this case the node is not starting at all and not writing anything in the log. I know from docs the changes need to be done in /config//jvm.options instead of changing root /config/jvm.options To make the cluster with es-7.16.2 and java 11 functional I had to change the root /config/jvm.options as described above. I had to use Java 11 to follow up the firm's requirement. I got your notes about using bundled java and elastic default settings but still have a few questions about configuration. Should I download and install it too?Īny help, suggestion on this issue resolution will be appreciated When I switch from Java 8 to Java 11 and changed the 'jdk1.8.0_281-amd64' for 'jdk-11.0.14' in the above script and run it then the node doesn't start and nothing even written in log fileĪm I missing something in Java 11 configuration or ES_JAVA_OPTS, or something else need to be changed in the above launching script to conform Java 11? Node starts gracefully with the appropriate entries in log file when referencing Java 8 in the script Įxport PATH=/usr/java/jdk1.8.0_281-amd64/binĮxport ES_KEYSTORE_PASSPHRASE_FILE=/path_to_file/es-keystore-sec.txtĬat /path_to_file/es-keystore-sec.txt | ES_JAVA_OPTS=_awareness_attributes=true -Xms4g -Xmx4g bin/elasticsearch -d -p /path_to_pid_file/es-pid > /dev/null 2>&1 & I'm starting es node with Java 8 (and without using bundled jdk) from launching script as follows.
