> Project: Hadoop YARN
> Issue Type: Bug

>
> The JobHistoryServer is leaking CLOSE_WAIT connections whenever viewing a
> huge log file in JobhistoryServer. This happens only when the below is
> configured.
> {code:java}
> yarn.log-aggregation.file-formats=IndexedFormat
> yarn.log-aggregation.file-controller.IndexedFormat.class=org.apache.hadoop.yarn.logaggregation.filecontroller.ifile.LogAggregationIndexedFileController
> yarn.log.server.url=http://jobhistory-host:19888/jobhistory/logs
> {code}
> On investigation, I found that the FSDataInputStream is not closed in
> org.apache.hadoop.yarn.logaggregation.filecontroller.ifile.IndexedFileAggregatedLogsBlock
> . Since this block is called every time the Josbhistory page displays the
> logs CLOSE_WAIT connections to datanode keep on increasing in
> JobHistoryServer.
