Description

HBase support replace -Xloggc:<FILE-PATH> for G1 or CMS。ZGC changed the format，like this：

-Xlog:safepoint,classhisto*=trace,age*,gc*=info:file=<FILE-PATH>:time,tid,tags:filecount=1,filesize=500M

Can  we only replace <FILE-PATH> instead of -Xloggc:<FILE-PATH> to support ZGC？

if [ -n "$SERVER_GC_OPTS" ]; then  
  export SERVER_GC_OPTS=${SERVER_GC_OPTS/"-Xloggc:<FILE-PATH>"/"-Xloggc:${HBASE_LOGGC}"}
fi
if [ -n "$CLIENT_GC_OPTS" ]; then  
  export CLIENT_GC_OPTS=${CLIENT_GC_OPTS/"-Xloggc:<FILE-PATH>"/"-Xloggc:${HBASE_LOGGC}"}
fi
