Rui Li updated HIVE-13525:
--------------------------
Attachment: HIVE-13525.3.patch
Update patch to solve the metrics lost problem.
Due to SPARK-14958, it's still possible the job can hang if task fails. What we
can do on our side to mitigate it is:
# Avoid task failure.
# Avoid deserialization error that triggers SPARK-14958.
For 1, the v3 patch makes HoS able to handle empty small table for map join.
For 2, the error that triggers SPARK-14958 is {{NoClassDefFoundError:
org/antlr/runtime/tree/CommonTree}}. So the v3 patch adds {{antlr-runtime}} to
driver's class path.
With the patch all the disabled tests can run (but may fail). I'll fix and
re-enable them in a follow on JIRA.
