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 On Mon, Jun 11, 2018 at 5:26 PM, Adam J.
