Review request for Ambari.
Bugs: AMBARI-20754
https://issues.apache.org/jira/browse/AMBARI-20754
Repository: ambari
Description
-------
get_value_from_jmx of jmx.py is used in getting NameNode HA state. As we know,
if the cluster is large, it takes a long time for Namenode to leave safe mode
when restarting Namenode, thus we use retry mechanism to invoke
get_value_from_jmx in case of getting wrong state. The problem is that,
get_value_from_jmx will print several exception message into std_error during
retrying, it confuses users because there're error messages in std_error, while
all the services restart successfully
