-------------------------------------
Summary: unresponsive !METADATA table seen on a very large cluster
Key: ACCUMULO-1408
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.
