> Issue Type: Bug
> Reporter: Zsolt Miskolczi

> Labels: pull-request-available

> Code:
> [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/tez/YarnQueueHelper.java#L203]
> h3. Summary
> The function *handleUnexpectedStatusCode()* in *YarnQueueHelper.java*
> sometimes fails to release a system resource allocated by *getErrorStream()*
> on line {*}206{*}.The program can potentially fail to release a system
> resource.
> h3. Explanation
> The program can potentially fail to release a system resource.
> In this case, there are program paths on which the resource allocated in
> *YarnQueueHelper.java* on line *203* is not released.
> Resource leaks have at least two common causes:
> - Error conditions and other exceptional circumstances.
> - Confusion over which part of the program is responsible for releasing the
> resource.
> Most unreleased resource issues result in general software reliability
> problems. However, if an attacker can intentionally trigger a resource leak,
> the attacker may be able to launch a denial of service attack by depleting
> the resource pool.
