Subject [jira] [Created] (HBASE-9887) Optimize client pause & back-off time
Date Mon, 04 Nov 2013 18:05:18 GMT
Nicolas Liochon created HBASE-9887:

             Summary: Optimize client pause & back-off time
                 Key: HBASE-9887
                 URL: https://issues.apache.org/jira/browse/HBASE-9887
             Project: HBase
          Issue Type: Brainstorming
          Components: Client
    Affects Versions: 0.96.0, 0.98.0
            Reporter: Nicolas Liochon
            Priority: Minor

The client can log all the retries, with this setting

We should use it to fix the pause time, as well as the back off.
I need to to a complete test, but on 100m, with the default config, I saw something like
5% of the first retry were successful
5% of ALL the retries between 2 and 6 were successful
90% of the retries between 7 and 9 were successful

So on this (too small) sample, the retries between 2 and 6 are nearly useless.

I will do a more complete test as well.
