Resolution: Duplicate
> 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
> Priority: Major
> 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.
