问题描述

HBase启动时，警告：
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0

解决办法

由于使用了JDK8 ，需要在HBase的配置文件中hbase-env.sh，注释掉两行。

[root@node1 ~]# vi /opt/hbase-1.2.5/conf/hbase-env.sh# Configure PermSize. Only needed in JDK7. You can safely remove it for JDK8+#export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m"#export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m"

重启

[root@node1 ~]# stop-hbase.shstopping hbase..........................[root@node1 ~]# start-hbase.shstarting master, logging to /opt/hbase-1.2.5/logs/hbase-root-master-node1.outnode3: starting regionserver, logging to /opt/hbase-1.2.5/logs/hbase-root-regionserver-node3.outnode2: starting regionserver, logging to /opt/hbase-1.2.5/logs/hbase-root-regionserver-node2.outnode1: starting regionserver, logging to /opt/hbase-1.2.5/logs/hbase-root-regionserver-node1.out
