First, the problem

When Hbase start, warning:

[hadoop@hadoop000 ~]$ start-hbase.sh 
starting master, logging to /home/hadoop/app/hbase-1.2.0-cdh5.7.0/logs/hbase-hadoop-master-hadoop000.out
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
hadoop000: starting regionserver, logging to /home/hadoop/app/hbase-1.2.0-cdh5.7.0/bin/../logs/hbase-hadoop-regionserver-hadoop000.out

Second, troubleshoot & resolve

1, Hbase installation process trophies Java has operational relationship, I was just $ HBASE_HOME / conf / hbase-env.sh file been configured, so go look at this file.

2, search for relevant content in this file, find the following:

# 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"

3, according to the explanatory notes, the two export commented out.

4, and then restart normal.

[hadoop@hadoop000 conf]$ start-hbase.sh
