Noe commented on HDFS-8406:
---------------------------
for those that run into this, but need to get system working again:
1) move problem wal to temp directory
2) then cp the file back into original location
> Lease recovery continually failed

> Key: HDFS-8406
> URL: https://issues.apache.org/jira/browse/HDFS-8406
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.6.0
> Reporter: Keith Turner
> Labels: Accumulo, HBase, SolrCloud
>
> While testing Accumulo on a cluster and killing processes, I ran into a
> situation where the lease on an accumulo write ahead log in HDFS could not be
> recovered. Even restarting HDFS and Accumulo would not fix the problem.
> The following message was seen in an Accumulo tablet server log immediately
> before the tablet server was killed.
