SummaryA guide to statistics that can be used to monitor region failures using Cloudera Manager. 
HBase region failures are handled by the HBase environment with little impact to the end user. 
However, a failure can occur that brings a region offline for a long time.  Currently there is not a default method to monitor for these failures.
