-------------------------------------

             Summary: HCatRecordObjectInspectorFactory is not thread safe
                 Key: HIVE-15773
                 URL: https://issues.apache.org/jira/browse/HIVE-15773
             Project: Hive
          Issue Type: Bug
            Reporter: David Phillips


{{HashMap}} used without synchronization for the caches, which makes the code unsafe for use in a multi-threaded environment such as Presto (or Spark?). The simple fix is to switch them to {{ConcurrentHashMap}}.
