Keith Turner updated ACCUMULO-317:
----------------------------------
Description:
When a FATE operation gets stuck, its hard to know whats happening. When I
first started looking into ACCUMULO-315 I knew a table operation was stuck.
But finding out which table and what operation was not easy. Need to write a
little utility that will print out information about current fate operations
and table locks held by fate operations.
It would be nice to have this before 1.4 ships as it will make debugging
problems in the field easier.
In addition to printing fate operations, we need a utility to fail and delete a
fate operations (and locks). This will give a workaround to unforseen bugs in
FATE operations. When things go bad a user can try to fail the operation and
if that does not work, they can delete it (which may leave the system in an
inconsistent state). Failing an operation should undo it.
