由于使用了JDK8 ，需要在HBase的配置文件中hbase-env.sh，注释掉两行。
代码语言：javascript复制[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
代码语言：javascript复制[root@node1 ~]# stop-hbase.sh
