Josh Rosen resolved SPARK-2527.
-------------------------------
Resolution: Cannot Reproduce
Assignee: Josh Rosen
I think that this was fixed in either 1.1 or 1.2 since I was unable to
reproduce this when writing a Selenium test to run your example script:
https://github.com/apache/spark/commit/bf589fc717c842d1998e3c3a523bc8775cb30269#diff-f346ada4cd59416756b6dd36b6c2605aR53
Therefore, I'm going to mark this as "Cannot Reproduce" since it was probably
fixed. Please re-open this ticket if you observe this in the wild with a newer
version of Spark.

> Key: SPARK-2527
> URL: https://issues.apache.org/jira/browse/SPARK-2527
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.0.0
> Reporter: Diana Carroll
> Assignee: Josh Rosen
> Attachments: persistbug1.png, persistbug2.png

>
> If I persist an RDD at one level, unpersist it, then repersist it at another
> level, the UI will continue to show the RDD at the first level...but
> correctly show individual partitions at the second level.
> {code}
> import org.apache.spark.api.java.StorageLevels
> import org.apache.spark.api.java.StorageLevels._
> val test1 = sc.parallelize(Array(1,2,3))test1.persist(StorageLevels.DISK_ONLY)
> test1.count()
> test1.unpersist()
> test1.persist(StorageLevels.MEMORY_ONLY)
> test1.count()
> {code}
> after the first call to persist and count, the Spark App web UI shows:
> RDD Storage Info for 14 Storage Level: Disk Serialized 1x Replicated
> rdd_14_0 Disk Serialized 1x Replicated
> After the second call, it shows:
> RDD Storage Info for 14 Storage Level: Disk Serialized 1x Replicated
> rdd_14_0 Memory Deserialized 1x Replicated
