> 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:
> {noformat}
> $ hbase shell

> 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|https://github.com/jruby/jruby/issues/2912] for details.

> 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.
