Date Tue, 04 Sep 2012 23:03:07 GMT

     [ https://issues.apache.org/jira/browse/KAFKA-449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

John Fung updated KAFKA-449:
----------------------------

    Attachment: kafka-449-v1.patch

Uploaded kafka-449-v1.patch with the following changes:

1. KAFKA-449: Support Leader Election Testcase for the following items:
1.a no. of iterations on bouncing the leader
1.b record the leader election latency
1.c configurable no. of partitions
1.d configurable no. of replication factor

2. KAFKA-482: Make producer to run during the entire duration of test. This is achieved by
launching the function of calling producer in a thread. When all the bouncing iterations are
done, an environment variable will be updated to signal producer to stop.

3. KAFKA-494: Relative paths should be used for svg URLs in dashboards html. This is changed
in order to make the graphic svg files to be accessible from inside a Hudson build report.

> The goal is to ensure that leader election completely successfully each time and also
record the leader election latency. Setup multiple partitions with a particular replication
factor. The test should take in the number of iterations. In each iteration, it bounces one
server. That server will be the leader for a certain set of partitions.  At the end of the
test, report the leader election latency along with message replication verification. The
test consists of several runs, each with a particular replication factor (between 1 and 6)
