[jira] [Commented] (SPARK-2090) spark-shell input text entry not
showing on REPL
[ https://issues.apache.org/jira/browse/SPARK-2090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14181273#comment-14181273 ]
sam commented on SPARK-2090:
----------------------------
I've experienced the same problem when I login to a cluster where my user doesn't have a user directory. Could someone catch the exception and print a meaningful message, e.g. "WARN: When you input text it may not display because you do not have a user directory"

> Key: SPARK-2090
> URL: https://issues.apache.org/jira/browse/SPARK-2090
> Project: Spark
> Issue Type: Bug
> Components: Input/Output, Spark Core
> Affects Versions: 1.0.0
> Environment: Ubuntu 14.04; Using Scala version 2.10.4 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_60)
> Reporter: Richard Conway
> Priority: Critical
> Labels: easyfix, patch
> Fix For: 1.0.0
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> spark-shell doesn't allow text to be displayed on input
> Failed to created SparkJLineReader: java.io.IOException: Permission denied
> Falling back to SimpleReader.
> The driver has 2 workers on 2 virtual machines and error free apart from the above line so I think it may have something to do with the introduction of the new SecurityManager.
> The upshot is that when you type nothing is displayed on the screen. For example, type "test" at the scala prompt and you won't see the input but the output will show.
> scala> <console>:11: error: package test is not a value
> test
> ^
