Review request for Ambari and Dmitro Lisnichenko.
Bugs: AMBARI-5763
https://issues.apache.org/jira/browse/AMBARI-5763
Repository: ambari
Description
-------
Nagios gets NN JMX metrics. When CorruptBlocks >0, it sends alert to the
administrator. However, the corrupted replica is not a concern, only corrupt
block should be a alert. Corrupt replica happens often in some environments and
this alert misleads some customers to think the data is lost.
The JMX metric "NumberOfMissingBlocks" is for corrupt block.
We want to do the following changes for Nagios alerting:
1) checks NumberOfMissingBlocks and sends alert when it's not zero. (already
doing this in current Ambari code??)
2) doesn't send alert for "CorruptBlocks" value change.
