Subject [jira] [Updated] (SPARK-15697) [SPARK REPL] unblock some of the useful repl commands.
Date Thu, 09 Jun 2016 09:17:21 GMT

     [ https://issues.apache.org/jira/browse/SPARK-15697?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prashant Sharma updated SPARK-15697:
------------------------------------
    Description: 
"implicits", "javap", "power", "type", "kind" commands in repl are blocked. However, they
work fine in all cases I have tried. It is clear we don't support them as they are part of
the scala/scala repl project. What is the harm in unblocking them, given they are useful ?
In previous versions of spark we disabled these commands because it was difficult to support
them without customization and the associated maintenance. Since the code base of scala repl
was actually ported and maintained under spark source. Now that is not the situation and one
can benefit from these commands in Spark REPL as much as in scala repl.

Symantics of reset are to be discussed in a separate issue.

In previous versions of spark we disabled these commands because it was difficult to support
them with out customization and the associated maintenance burden. 

Symantics of reset are to be discussed in a separate issue.
