Change subject: IMPALA-14278: Fix MemTracker data race between ExecEnv and Webserver ...................................................................... IMPALA-14278: Fix MemTracker data race between ExecEnv and Webserver In the Webserver, while assigning or closing the compressed buffer's memory tracker, no lock was being held across threads causing TSAN build failures. The critical section for this memory tracker is only necessary during begining of the Webserver and is used rarely. So, only a general mutex has been used instead of a shared mutex with concurrent reads.
