Subject [jira] [Resolved] (HBASE-15199) Move jruby jar so only on hbase-shell module classpath; currently globally available
Date Wed, 03 May 2017 17:42:04 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Busbey resolved HBASE-15199.
---------------------------------
      Resolution: Fixed
    Hadoop Flags: Incompatible change
    Release Note: The JRuby jar is no longer automatically included in classpaths for HBase
server processes nor clients. It is still included in the classpath for the HBase shell and
for invocations of org.jruby.Main, which should cover HBase provided support scripts.

> A suggestion that came up out of internal issue (filed by Mr Jan Van Besien) was to move
the scope of the jruby include down so it is only a dependency for the hbase-shell. jruby
jar brings in a bunch of dependencies (joda time for example) which can clash with the includes
of others. Our Sean suggests that could be good to shut down exploit possibilities if jruby
was not globally available. Only downside I can think is that it may no longer be available
to our bin/*rb scripts if we move the jar but perhaps these can be changed so they can find
the ruby jar in new location.
