> URL: https://issues.apache.org/jira/browse/ACCUMULO-1408
> Project: Accumulo
> Issue Type: Bug
> Components: tserver
> Affects Versions: 1.4.3
> Environment: large cluster
> Reporter: Eric Newton
> Assignee: Eric Newton
>
> On a large cluster, saw an unresponsive !METADATA table; this resulted in
> hundreds of simultaneous scans of the root tablet. tservers did not look
> busy. They had lots of data available on their recv network queues, and
> nothing out their output queues. Most of these recv buffers did not change
> over time. After killing these unresponsive servers the system recovered.
> HDFS was about 80% full.
> accumulo was running over CDH3u5.
