--------------------------------------
Summary: Various fixes in client code
Key: HBASE-9843
URL: https://issues.apache.org/jira/browse/HBASE-9843
Project: HBase
Issue Type: Bug
Components: Client
Affects Versions: 0.96.0
Reporter: Nicolas Liochon
Assignee: Nicolas Liochon
Fix For: 0.98.0, 0.96.1
This mainly fixes issues when we had "long" errors, for example a multi blocked
when trying to obtain a lock that was finally failing after 60s. Previously we
were trying only for 5 minutes. We now do all the tries. I've fixed stuff
around this area to make it work.
There is also more logs.
I've changed the back off array. With the default pause of 100ms, even after 20
tries we still retry every 10s.
I've also changed the max per RS to something minimal. If the cluster is not in
a very good state it's less aggressive. It seems to be a better default.
I've done two tests:
- on a small; homogeneous cluster, I had the same performances
- on a bigger, but heterogeneous cluster it was twice as fast.
