Description
I made a mistake while after re-enabling a table on which I did an `alter' to add a coprocessor: the .jar I specified wasn't a self-contained jar, and thus some dependent classes couldn't be found.

The master retried 10 times and then seems to have given up. I'm trying to point it to a different jar, but I can't, and the table now seems stuck in a not-enabled-nor-disabled state:
