Subject [jira] Commented: (HDFS-708) A stress-test tool for HDFS.
Date Tue, 26 Jan 2010 04:12:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12804881#action_12804881

Konstantin Boudnik commented on HDFS-708:
-----------------------------------------

I'd suggest to call it 'load-test tool' for the sake of correct definitions. The purpose of
this tool isn't to _crash_ the system but rather to see it works under a significant load.
That said, with a certain argument value the system might be exercised to the point of failure.
However, that scenario is about a stressful application of the said load tool.

> It would be good to have a tool for automatic stress testing HDFS, which would provide
IO-intensive load on HDFS cluster.
> The idea is to start the tool, let it run overnight, and then be able to analyze possible
failures.
