> Accumulo Tablet Server failed to retain lock with ZooKeeper
> -----------------------------------------------------------
>
> Key: ACCUMULO-2313
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2313
> Project: Accumulo
> Issue Type: Bug
> Components: tserver
> Affects Versions: 1.5.0
> Environment: 40 Node Cluster
> Each Node: 64GB RAM, 8 Cores (2.4 GHz) , 4x1.5TB drives, 10 Gb/s Ethernet
> Reporter: Glenn Primmer
>
> On 3 Nodes the Accumulo Tservers did not communicate with ZooKeeper within
> the timeout period and therefor lost their locks. Looking at the resource
> utilization (Nagios) it did not appear that the node CPU/resource utilization
> was a factor as to why Accumulo Tservers did not communicate with ZooKeeper
> within the timeout period.
> Question is, is there potential thread contention for the thread responsible
> for retaining the ZooKeeper lock in the Accumulo Tservers?
