Subject Fixing a messed up WAL file
Date Mon, 06 Aug 2012 02:58:38 GMT
In regards to ACCUMULO-716, I'm having some issues "gracefully" 
recovering from a corrupt WAL file (read-as, I don't want to blow away 
ZK and reinitialize).

I moved the bad file in HDFS out of ${instance.dfs.dir}/wal and then 
attempted to update zookeeper to remove the entry for that bad file, 
e.g. /accumulo/${}/root_tablet/walogs/bad-file. I couldn't 
get around the lack of authorization to delete the file via zkCli nor 
could I replicate the deletion logic piecing together Accumulo code.

Is there a utility I missed somewhere that launches a ZK shell with the 
correct credentials with which I could actually manipulate the protected 

If memory serves me, the ZK authorization I was missing is related to 
the root username/password for the instance. Is this actually the case 
or did I dream that up? If so, something like `addauth digest
