Tianying Chang created HBASE-7816:
-------------------------------------
Summary: numericPersistentMetrics should be not be cleared for
regions that are not being closed.
Key: HBASE-7816
URL: https://issues.apache.org/jira/browse/HBASE-7816
Project: HBase
Issue Type: Bug
Components: metrics
Affects Versions: 0.94.4
Reporter: Tianying Chang
Assignee: Tianying Chang
Fix For: 0.94.4
when a region is closed, the region level dynamic metrics
"numericPersistentMetrics" are cleared for all regions on the same region
servers. It is OK for numericMetrics and timeVaryingMetrics. But not right for
numericPersistentMetrics, because those value are accumulated and not be reset
at poll time. To keep the right value, only the metrics for the closed region
should be cleared, numericPersistentMetrics for other regions should be kept.
