YulongZ commented on HIVE-19439:
--------------------------------
{code:java}
// Operator::initialize()
if (state == State.INIT){
return;
} {code}
Whether state is State.INIT or not, maybe we continue to force initialization
for HOS.
> MapWork shouldn't be reused when Spark task fails during initialization

> Project: Hive
> Issue Type: Bug
> Components: Spark
> Reporter: Rui Li
> Priority: Major

> Issue identified in HIVE-19388. When a Spark task fails during initializing
> the map operator, the task is retried with the same MapWork retrieved from
> cache. This can be problematic because the MapWork may be partially
> initialized, e.g. some operators are already in INIT state.
