H100 Unable to submit statement show databases like '*': org.apache.thrift.transport.TTransportException: java.net.SocketException: Broken pipe"

The Ambari view throws the following error: H100 Unable to submit statement show databases like '*': org.apache.thrift.transport.TTransportException:java.net.SocketTimeoutException: Read timed out And I can no longer view database or run queries in the Ambari view. The problem appears to resolve itself after some time, but then will reappear after running a sequence of queries in the Hive view.

1) This should be fixed in Ambari 2.2

2) Browser Refresh fixed it: When connection was open for too long then there was a broken pipe when you tried to access the hive view. When you did a restart to opened a fresh connection and was able to connect.
