--------------------------------
Summary: NumTimedOutPendingReconstructions metrics should not be
accumulated
Key: HDFS-16994
URL: https://issues.apache.org/jira/browse/HDFS-16994
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: farmmamba
For now, the NumTimedOutPendingReconstructions metric is computed by below
statement:
{code:java}
timedOutCount + timedOutItems.size(); {code}
Therefore, its value would always be accumulated unless namenode failover
happens.
In fact, the NumTimedOutPendingReconstructions metric should not be
accumulated, So, we should set it to zero after we execute getNumTimedOuts
method.
The UT TestPendingReconstruction#testPendingReconstruction was passed.
