Subject [jira] [Updated] (HBASE-8438) Extend bin/hbase to print a "minimal classpath" for used by other tools
Date Wed, 13 Nov 2013 00:13:19 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8438?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Nick Dimiduk updated HBASE-8438:

    Attachment: 0001-HBASE-8438-Extend-bin-hbase-to-print-a-minimal-class.patch

Simplified implementation. Since we already manually maintain a list of mapreduce dependencies
over in TableMapReduceUtils, why not use it? This version builds on addDependencyJars and
exposes it on the command line via a simple utility.

> For tools like pig and hive, blindly appending the full output of `bin/hbase classpath`
to their own CLASSPATH is excessive. They already build CLASSPATH entries for hadoop. All
they need from us is the delta entries, the dependencies we require w/o hadoop and all of
it's transitive deps. This is also a kindness for Windows, where there's a shorter limit on
the length of commandline arguments.
