> Support same timeout operations in mapGroupsWithState function in batch

> Key: SPARK-20792
> URL: https://issues.apache.org/jira/browse/SPARK-20792
> Project: Spark
> Issue Type: Sub-task
> Components: Structured Streaming
> Affects Versions: 2.2.0
> Reporter: Tathagata Das

> Fix For: 2.2.0

>
> Currently, in the batch queries, timeout is disabled (i.e.
> GroupStateTimeout.NoTimeout) which means any GroupState.setTimeout***
> operation would throw UnsupportedOperationException. This makes it weird when
> converting a streaming query into a batch query by changing the input DF from
> streaming to a batch DF. If the timeout was enabled and used, then the batch
> query will start throwing UnsupportedOperationException.
