> 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.
