Description
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):
HBase Shell Use "help" to get list of supported commands. Use "exit" to quit this interactive shell.
