Is the message you are seeing "COMPACTION_FINISH (without preceding
COMPACTION_START)" ?  That messages indicates that the WALs are
incomplete, probably as a result of the NN problems.  Could do the
following :

1) Run the following command to see whats in the log.  Need to see
what is there for the root tablet.

   accumulo org.apache.accumulo.tserver.logger.LogReader

2) Replace the log file with an empty file after seeing if there is
anything important in it.

I think the list of WALs for the root tablet is stored in ZK at
/accumulo/<id>/walogs
