about JDK Version for hbase

Contributor

Dear all.

 

I have a hbase cluster using JDK 1.7 and G1GC and CentOS6.10.

Sometimes a region server shutdown unexpectedly.

There is no log about the shutdown in the hbase region server log file.

But it remains crash log in the /var/run/cloudera-scm-agent/process/3643-REGIONSERVER/hs_err_pid142004.log 

Do you have any idea of this symtoms?

Is it okay to change one of region servers JDK version from 1.7 to 1.8?

 

Below is the head of crash log.
