     [ https://issues.apache.org/jira/browse/SPARK-2090?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Richard Conway resolved SPARK-2090.
-----------------------------------

    Resolution: Not a Problem

This is to do with the permissions on the home directory manifesting itself in the Scala REPL as not being able to echo input.

>                 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
>               ^
