--------------------------------------
Summary: [0.89-fb] Fast fail client operations if the regionserver
is repeatedly unreachable.
Key: HBASE-6629
URL: https://issues.apache.org/jira/browse/HBASE-6629
Project: HBase
Issue Type: Bug
Reporter: Amitanand Aiyer
Priority: Minor
We have seen occassional RSW reboots in the production cluster.
On the client end, the reduction in the operation throughput is a lot more than
the %-age of nodes disconnected. This is because operations to the disconnected
machines are holding up resources that could otherwise be used for successful
operation.
This change enables the client to detect when there are repeated failures to a
regionserver, and fast fail operations so we do not hold up resources.
