Hi All,
I have reams of errors in my master log for a single region. It keeps
trying and failing to open the region. An example of the exception is below.
Are there conceivable ways of fixing this or am I most likely going to have
to delete the region. If deleting the region is the likely option, are
there any tools to help with this? I saw the recent message from Stack
describing how to delete a region. Does that mean I have to manually edit
.META. from the hbase shell? Do I also have to edit the .regioninfo files
in the modified regions' directories with the new start/end keys?
Thanks!
