> 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.
