             Summary: Support same timeout operations in mapGroupsWithState function in batch queries as in streaming queries
                 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
            Assignee: Tathagata Das


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.
