Subject [jira] [Updated] (HBASE-16196) Update jruby to a newer version.
Date Wed, 27 Jul 2016 22:43:20 GMT

     [ https://issues.apache.org/jira/browse/HBASE-16196?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Matt Mullins updated HBASE-16196:
    Attachment: hbase-16196.v2.branch-1.patch

Agreed on testing {{region_mover.rb}}; I've included some changes in v2 that get it to run
on my development machine, but I will test it manually on a distributed cluster as well. 
I'll also make sure that the other Ruby scripts in bin/ work.

Attached an updated patch with the following changes that seem to satisfy the testsuite:
* The shell's exception handling has been updated to handle Ruby 2.1's addition of Exception#cause
- this patch continues to throw a Ruby RuntimeError instead of walking the chain of .cause()
to the native Java exception.
* {{Hbase::Admin#describe}} now checks the existence of a table like many other commands,
in order to throw a Ruby exception rather than a Java native exception.  The test for Admin#describe
now calls it with a non-existent but otherwise legal table name.  This was previous the only
test using an illegal name (which results in a Java-native IllegalArgumentException instead).
* setLoadPaths() is now on the ScriptingContainer in JRuby.
* region_mover.rb is minimally changed due to {{require}} loading being slightly different.

>         Attachments: 0001-Update-to-JRuby-, hbase-16196.branch-1.patch,
> Ruby 1.8.7 is no longer maintained.
> The TTY library in the old jruby is bad. The newer one is less bad.
> Since this is only a dependency on the hbase-shell module and not on hbase-client or
hbase-server this should be a pretty simple thing that doesn't have any backwards compat issues.
