> Over in hbase-2177 Ryan goes on how enabling gc logging, it shows on stdout
> when you fire the shell:
> {code}
> so one problem with this is the irb then logs all GC to stdout, which is
> ugly. I do something like this in my scripts:
> export HBASE_OPTS=""
> export HBASE_LOG_DIR=<somewhere>
> export SERVER_GC_OPTS="$HBASE_OPTS -verbose:gc
> -XX:+PrintGCApplicationStoppedTime -XX:+PrintGCDateStamps -XX:+PrintGCDetails
> -Xloggc:$HBASE_HOME/logs/gc-hbase.log"
> export JMX_OPTS="-Dcom.sun.management.jmxremote.authenticate=true
> -Dcom.sun.management.jmxremote.ssl=false
> -Dcom.sun.management.jmxremote.password.file=$HBASE_HOME/conf/jmxremote.password
> -Dcom.sun.management.jmxremote"
> export HBASE_MASTER_OPTS="$SERVER_GC_OPTS
> -Xloggc:$HBASE_LOG_DIR/logs/gc-master.log"
> export HBASE_REGIONSERVER_OPTS="$SERVER_GC_OPTS
> -Xloggc:$HBASE_LOG_DIR/gc-hbase.log -Dcom.sun.management.jmxremote.port=10102
> $JMX_OPTS"
> export HBASE_THRIFT_OPTS="-Xmx1000m $SERVER_GC_OPTS
> -Xloggc:$HBASE_LOG_DIR/gc-hbase-thrift.log
> -Dcom.sun.management.jmxremote.port=10103 $JMX_OPTS"
> export HBASE_ZOOKEEPER_OPTS="-Xmx1000m $SERVER_GC_OPTS
> -Xloggc:$HBASE_LOG_DIR/gc-zk.log -Dcom.sun.management.jmxremote.port=10104
> $JMX_OPTS"
> now you get remote JMX with logging to whatever directory (we have to log to
> our large data partition since logs... can be big). Also the shell doesnt
> log GC to stdout, and you can get separate GC logs for hmaster, hrs, thrift,
> zookeeper.
> {code}
> Need to make an OPTS for the shell to use.... or do the above.
