[jira] [Created] (HIVE-10052) HiveInputFormat implementations getsplits may lead to memory leak.[Spark Branch]

Chengxiang Li created HIVE-10052:
------------------------------------

             Summary: HiveInputFormat implementations getsplits may lead to memory leak.[Spark Branch]
                 Key: HIVE-10052
                 URL: https://issues.apache.org/jira/browse/HIVE-10052
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Chengxiang Li


HiveInputFormat::init would cache MapWork/ReduceWork in ThreadLocal map, we need to clear the cache after getSplits from HiveInputFormat(or its implementations), or just not cache MapWork/ReduceWork during generation.
