Duo Zhang commented on HBASE-24885:
-----------------------------------
So this is only a proble for HBCK2? Then I think it is the caller's duty to
make sure that you do not do something wrong... HBCK2 is for fixing assignment
problems, so the method is designed to skip all the checks and force to do an
assignment...
This is the comment of the method
{code}
/**
* A 'raw' version of assign that does bulk and skirts Master state checks
(assigns can be made
* during Master startup). For use by Hbck2.
*/
{code}
> STUCK RIT by hbck2 assigns
