Subject [jira] [Commented] (INFRA-5046) Apache Giraph reviewboard not working correctly
Date Tue, 14 Aug 2012 07:46:38 GMT


Avery Ching commented on INFRA-5046:

Gavin, thanks again for all your help!  There are still a few issues with reviewboard that
we could really use your help on.  Please let us know if you are not the right person to contact.

1) Reviewboard used to automatically post to the relevant JIRA based on the "Bugs: entry".
 For instance, should have posted to
 This no longer happens.

2) I am still getting moderate reviews for every reviewboard posting.  Have you seen this
for other projects?  It seemed to also have occurred after the move out of the incubator.
 Would really appreciate your help with this one as well.

Review request for giraph.
By Avery Ching.

* Upgrade to the most recent stable version of Netty (3.5.3.Final)
* Try multiple connection attempts up to n failures
* Track requests throughout the system by keeping track of the request id and then matching
the request id to the response (minor refactoring of WritableRequest to make requests simpler
and support the request id)
* Improved handling of netty exceptions by dumping the exception stack to help debug failures
* Fixes bug in HashWorkerPartitioner by making partitionList thread-safe (this causes divide
by zero exceptions in real life)


Currently, netty connection failures causes issues with more than 75 workers in my setup.
This allows us to reach over 200+ in a reasonably reliable network that doesn't kill connections.

This code passes the local Hadoop regressions and the single node Hadoop instance regressions.
It also succeeded on large runs (200+ workers) on a real Hadoop cluster.
