Subject locked fate threads
Date Thu, 05 Sep 2013 12:00:26 GMT
I recently tried to remove some tables, during which I was getting a shell thread stuck on
IO error.  A fate print plus some digging into the logs revealed they were stuck waiting on
WAL resources.  I found a thread in which Eric Newton explained how to manually remove the
tables removing lines from the !METADATA table using "deletemany -c file," then cleaning up
the /accumulo/tables/<id> in hdfs.  I've done that, however the fate threads are still
locked and I am unable to delete or fail them.  Additionally, the tables I removed from !METADATA
and hdfs still appear in the list returned by the "tables" command in shell.  Below is the
result of a "fate print."  To note, tables id a and b are the two which I've removed.
