Subject [jira] [Updated] (HDFS-8406) Lease recovery continually failed
Date Wed, 24 Jun 2015 19:21:05 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8406?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Drob updated HDFS-8406:
----------------------------
    Labels: Accumulo HBase SolrCloud  (was: Accumulo HBase)

I'm pretty sure I've seen this in SolrCloud during recovery as well. Thanks for filing, Keith!

> Lease recovery continually failed

>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 2.6.0
>            Reporter: Keith Turner

> 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.
