--------------------------------------
Summary: Unreleased resource in YarnQueueHelper
Key: HIVE-29876
URL: https://issues.apache.org/jira/browse/HIVE-29876
Project: Hive
Issue Type: Bug
Reporter: Zsolt Miskolczi
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.
