Benoit Sigoure created HBASE-9936:
-------------------------------------
Summary: Table get stuck when it fails to open due to a
coprocessor error
Key: HBASE-9936
URL: https://issues.apache.org/jira/browse/HBASE-9936
Project: HBase
Issue Type: Bug
Affects Versions: 0.96.0
Reporter: Benoit Sigoure
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:
