> Fix potential thread safety issues with static variables
> --------------------------------------------------------
>
> Key: HIVE-16183
> URL: https://issues.apache.org/jira/browse/HIVE-16183
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Attachments: HIVE-16183.1.patch, HIVE-16183.patch
>
>
> Many concurrency issues (HIVE-12768, HIVE-16175, HIVE-16060) have been found
> with respect to class static variable usages. With fact that HS2 supports
> concurrent compilation and task execution as well as some backend engines
> (such as Spark) running multiple tasks in a single JVM, traditional
> assumption (or mindset) of single threaded execution needs to be abandoned.
> This purpose of this JIRA is to do a global scan of static variables in Hive
> code base, and correct potential thread-safety issues. However, it's not
> meant to be exhaustive.
