Review request for Ambari, Jonathan Hurley and Sumit Mohanty.


Bugs: AMBARI-12980
    https://issues.apache.org/jira/browse/AMBARI-12980


Repository: ambari


Description
-------

Alert Type = METRIC
Lets add a new Alert for HDFS based on PendingDeletionBlocks. This is a JMX data point FSNamesystem
--> PendingDeletionBlocks.
This alert could potentially be designed based on NameNode Blocks Health. Warning and Critical
both can be issued when the value exceeds 100,000. These thresholds should be configurable.

Diff: https://reviews.apache.org/r/38062/diff/


Testing
-------

mvn clean test


Thanks,

Vitalyi Brodetskyi
