>                 URL: https://issues.apache.org/jira/browse/HDFS-16994
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>            Reporter: farmmamba
>            Priority: Minor
>              Labels: pull-request-available
>
> 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.
