Jimmy Xiang commented on HBASE-7521:
------------------------------------
This patch removed a method from RegionServerServices. If some coprocessor
happens to use it, it will be broken. It also added two new methods to this
class. Other than that, I don't see other rolling restart/compatibility issue.
However, the chance for a coprocessor to use these methods are very low.

> Discussion in HBASE-6060 implies that the fix there does not work on 0.94.
> Still, we may want to fix the issue in 0.94 (via some different fix) because
> the regions stuck in opening for ridiculous amounts of time is not a good
> thing to have.
