------------------------------------
Summary: Cleanup unused lock in MultiVersionConsistencyControl in
branch-1.0 and 1.1
Key: HBASE-15819
URL: https://issues.apache.org/jira/browse/HBASE-15819
Project: HBase
Issue Type: Bug
Components: regionserver
Reporter: Jingcheng Du
Assignee: Jingcheng Du
In MultiVersionConsistencyControl of branch-1.0 and branch-1.1, there is a
unused lock readWaiters, it is only referenced by {{boolean
advanceMemstore(WriteEntry e)}},
{code}
if (nextReadValue > 0) {
synchronized (readWaiters) {
readWaiters.notifyAll();
}
}
{code}.
Thus the readerWaiters.notifyAll() is not necessary, and could be cleaned up
from the code.
