fix remoteinterpreterserver deadlock problem
After using zeppelin server for some days, we often found that paragraph
can't run while the zeppelin server process is on, restart interpreter is just
not work. Then we find out that the RemoteInterpreterServer is in deadlock, and
can't be stopped by zeppelin server. Unfortunately, this deadlocked
RemoteInterpreterServer will still hold the hadoop resources, we need to kill
the process manually each time. The detail Info shows in:
https://issues.apache.org/jira/browse/ZEPPELIN-271
We figure out that the deadlock is caused by the lack of synchronized
(intpGroup) in SparkSqlInterpreter.java
