-------------------------------------
Summary: Replication can report incorrect size of log queue for
the global source when multiwal is enabled
Key: HBASE-15093
URL: https://issues.apache.org/jira/browse/HBASE-15093
Project: HBase
Issue Type: Bug
Components: Replication
Affects Versions: 2.0.0, 1.2.0, 1.2.1
Reporter: Ashu Pachauri
Assignee: Ashu Pachauri
Priority: Minor
Replication can report incorrect size for the size of log queue for the global
source when multiwal is enabled. This happens because the method
MetricsSource#setSizeofLogQueue performs non-trivial operations in a
multithreaded world, even though it is not synchronized.
We can simply divide MetricsSource#setSizeofLogQueue into
MetricsSource#incrSizeofLogQueue and MetricsSource#decrSizeofLogQueue. Not sure
why we are currently directly setting the size instead of
incrementing/decrementing it.
