[jira] [Commented] (SPARK-9044) Updated RDD name does not reflect under "Storage" tab

["Zhang, Liye (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-9044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14627472#comment-14627472 ] 

Zhang, Liye commented on SPARK-9044:
------------------------------------

It's a bug, since RDD is identified by rdd.id and it is immutable, if we only change the name, the RDD is stay the same (cached), and the blockManager would not regard that there is blocks to update, so the metrics would not get updated. So the RDDInfo will not be updated also.

> I was playing the spark-shell in my macbook, here is what I did:
> scala> val textFile = sc.textFile("/Users/jackzhang/Downloads/ProdPart.txt");
> scala> textFile.cache
> scala> textFile.setName("test1")
> scala> textFile.collect
> scala> textFile.name
> res10: String = test1
> After this four commands, I can see the "test1" RDD listed in the "Storage" tab.
> However, if I continually run following commands, nothing will happen from the "Storage" tab:
> scala> textFile.setName("test2")
> scala> textFile.cache
> scala> textFile.collect
> scala> textFile.name
> res10: String = test2
> I am expecting the name of the RDD shows in "Storage" tab should be "test2", is this a bug?
