[jira] [Created] (SPARK-18749) CLONE - checkpointLocation being set in memory streams fail after restart. Should fail fast

Michael Armbrust created SPARK-18749:
----------------------------------------

             Summary: CLONE - checkpointLocation being set in memory streams fail after restart. Should fail fast
                 Key: SPARK-18749
                 URL: https://issues.apache.org/jira/browse/SPARK-18749
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 2.0.0, 2.0.1
            Reporter: Burak Yavuz


The checkpointLocation option in memory streams in StructuredStreaming is not used during recovery. However, it can use this location if it is being set. However, during recovery, if this location was set, we get an exception saying that we will not use this location for recovery, please delete it. 

It's better to just fail before you start the stream in the first place
