Baoxu Shi updated SPARK-2228:
-----------------------------
Description:
We are using `SaveAsObjectFile` and `objectFile` to cut off lineage during
iterative computing, but after several hundreds of iterations, there will be
`NoSuchElementsError`. We check the code and locate the problem at
`org.apache.spark.ui.jobs.JobProgressListener`. When `onStageCompleted` is
called, such `stageId` can not be found in `stageIdToPool`, but it does exist
in other HashMaps. So we think `onStageSubmitted` is not properly called.
`Spark` did add a stage but failed to send the message to listeners. When
sending `finish` message to listeners, the error occurs.
This problem will cause a huge number of `active stages` showing in `SparkUI`,
which is really annoying. But it may not affect the final result, according to
the result of my testing code.
I'm willing to help solve this problem, any idea about which part should I
change? I assume `org.apache.spark.scheduler.SparkListenerBus` have something
to do with it but it looks fine to me.
FYI, here is the test code that could reproduce the problem. I do not know who
to put code here with highlight, so I put the code on gist to make the issue
looks clean.
