What does (### skipped) mean in the Spark UI?
We just upgraded to Spark 1.2.0 and we're seeing this in the UI.

Looks like the number of skipped stages couldn't be formatted. Cheers On Wed, Jan 7, 2015 at 12:08 PM, Corey Nolet wrote: > We just upgraded to Spark 1.2.0 and we're seeing this in the UI. >

Sorry- replace ### with an actual number. What does a "skipped" stage mean? I'm running a series of jobs and it seems like after a certain point, the number of skipped stages is larger than the number of actual completed stages.

+Josh, who added the Job UI page. I've seen this as well and was a bit confused about what it meant. Josh, is there a specific scenario that creates these skipped stages in the Job UI ?

That's what you want to see. The computation of a stage is skipped if the results for that stage are still available from the evaluation of a prior job run: https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/ui/jobs/JobProgressListener.scala#L163 On Wed, Jan 7, 2015 at 12:32 PM, Corey Nolet wrote: > Sorry- replace ### with an actual number.

Ah I see - So its more like 're-used stages' which is not necessarily a bug in the program or something like that.
