Summary: Add new shell command 'rit' for listing regions in transition
Key: HBASE-21283
URL: https://issues.apache.org/jira/browse/HBASE-21283
Project: HBase
Issue Type: Improvement
Reporter: Andrew Purtell
Assignee: Andrew Purtell
Fix For: 3.0.0, 1.5.0, 2.2.0


The 'status' shell command shows regions in transition but sometimes an operator may want to retrieve a simple list of regions in transition. Here's a patch that adds a new 'rit' command to the TOOLS group that does just that.

No test, because it seems hard to mock RITs from the ruby test code, but I have run TestShell and it passes, so the command is verified to meet minimum requirements, like help text, and manually verified with branch-1 (shell in branch-2 and up doesn't return until TransitRegionProcedure has completed so by that time no RIT):
