Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-12898
    https://issues.apache.org/jira/browse/AMBARI-12898


Repository: ambari


Description
-------

Reference linked.  
In hdfs-site.xml, dfs.content-summary.limit should be set to 5000 by default.  
The getContentSummary call causes long pauses in NN if it is called on the
root "/". This configuration will avoid holding FSN lock for too long.
