-----------------------------------------------
@Ted, thanks for the review.
We need to delete the node in zookeeper which is in offline state. Because as
part of recovery when we try to enable the table , the regions of the table
may be already onlined so we just try to delete the node created for that
region.
If we dont delete the node, scans can be performed but if we try to disable the
table it may not work as already the node is created in zookeeper.
So thats why any failure while deleting the node i thouhgt of aborting the
master which is the way we have handled in
public void offlineDisabledRegion(HRegionInfo regionInfo) and in
OpenedRegionHandler.process() api.
Please provide your comments.
