Joshua Harlow commented on HDFS-708: ------------------------------------ 1. Done 2. Done 3. These methods have meanings for null (mainly for default checks for existence for merging) and a random seed meaning null means no seed which is possible. Duration for milliseconds can return an int though. Just that null has a meaning if the default value for a config option is set to be a null object. Which it is in a couple of cases. 4 & 5. Done (we are no measuring only the time around readByte and write()) 6. Done 7. Done 8. Done 9 & 10. Done 11. Done and most classes made package private 15. Will add some tests. > A stress-test tool for HDFS. > ---------------------------- > > Key: HDFS-708 > URL: https://issues.apache.org/jira/browse/HDFS-708 > Project: Hadoop HDFS > Issue Type: New Feature > Components: test, tools > Affects Versions: 0.22.0 > Reporter: Konstantin Shvachko > Assignee: Joshua Harlow > Fix For: 0.22.0 > > Attachments: slive.patch, SLiveTest.pdf > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
