Lefty Leverenz commented on HIVE-15541:
---------------------------------------
Doc note: This adds *hive.ats.hook.queue.capacity* to HiveConf.java, so it
needs to be documented in the wiki for release 2.2.0.
* [Configuration Properties -- Query and DDL Execution |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]
Added a TODOC2.2 label.

> The ATS API used by the Hive ATSHook is a blocking call, if ATS goes down
> this can block the ATSHook executor, while the hook continues to submit work
> to the executor with each query.
> Over time the buildup of queued items can cause OOM.
