---------------------------------
Summary: Retrying task could use cached bad operators [Spark
Branch]
Key: HIVE-9993
URL: https://issues.apache.org/jira/browse/HIVE-9993
Project: Hive
Issue Type: Bug
Affects Versions: spark-branch
Reporter: Jimmy Xiang
Assignee: Jimmy Xiang
Fix For: spark-branch
For a Spark task, it could be retried on the same executor in case some
failures. In retrying, the cache task could be used. Since the operators in the
task are already initialized, they won't be initialized again. The partial data
in these operators could lead to wrong final results.
