> HBase support replace -Xloggc:<FILE-PATH> for G1 or CMS。ZGC changed the format，like this：
> {code:java}
> -Xlog:safepoint,classhisto*=trace,age*,gc*=info:file=<FILE-PATH>:time,tid,tags:filecount=1,filesize=500M{code}
> Can  we only replace <FILE-PATH> instead of -Xloggc:<FILE-PATH> to support ZGC？
> [https://github.com/apache/hbase/blob/master/bin/hbase-daemon.sh#L174]
> {code:java}
> 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 {code}
