             Summary: ConsoleSink should not fail streaming query with checkpointLocation option
                 Key: SPARK-21667
                 URL: https://issues.apache.org/jira/browse/SPARK-21667
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 2.3.0
            Reporter: Jacek Laskowski
            Priority: Minor


As agreed on the Spark users mailing list in the thread "\[SS] Console sink not supporting recovering from checkpoint location? Why?" in which [~marmbrus] said:

I think there is really no good reason for this limitation.

Using {{ConsoleSink}} should therefore not fail a streaming query when used with {{checkpointLocation}} option.

{code}
// today's build from the master
scala> spark.version
res8: String = 2.3.0-SNAPSHOT

scala> val q = records.
     |   writeStream.
     |   format("console").
     |   option("truncate", false).
     |   option("checkpointLocation", "/tmp/checkpoint"). // <--
checkpoint directory
     |   trigger(Trigger.ProcessingTime(10.seconds)).
     |   outputMode(OutputMode.Update).
     |   start
org.apache.spark.sql.AnalysisException: This query does not support recovering from checkpoint location. Delete /tmp/checkpoint/offsets to start over.;
  at org.apache.spark.sql.streaming.StreamingQueryManager.createQuery(StreamingQueryManager.scala:222)

  at org.apache.spark.sql.streaming.DataStreamWriter.start(DataStreamWriter.scala:284)
  ... 61 elided
{code}

The "trigger" is SPARK-16116 and [this line|https://github.com/apache/spark/pull/13817/files#diff-d35e8fce09686073f81de598ed657de7R277] in particular.

This also relates to SPARK-19768 that was resolved as not a bug.
