Description

After upgrading HBase to 1.1.9 in BIGTOP-2740, the HMaster and RegionServer processes look good on ppc64le. This is a significant improvement, as the previous version (1.1.3) did not work at all.

However, hbase shell still fails like this with 1.1.9:

$ hbase shell

     initialize at /usr/lib/hbase/lib/ruby/shell/formatter.rb:48
         (root) at /usr/lib/hbase/bin/hirb.rb:116

This stems from an incompatibility in the JLine version that ships with the updated JRuby lib (which is required for ppc64le). See HBASE-13338 and jruby issue for details.

You can work around this by patching formatter.rb:

It's not ideal, but it's a simple enough workaround for anyone needing hbase shell on ppc64le.

I'm opening this jira to determine how best to apply this workaround, or where to document this as a limitation of HBase 1.1.x on ppc64le.
