Doug Cutting commented on HADOOP-132: ------------------------------------- We should still stick with JDK 1.4. Most developers are now using JDK 1.5, but many folks still use JDK 1.4 in production. So, if it's not too much pain, please back-port this to 1.4. Thanks! > An API for reporting performance metrics > ---------------------------------------- > > Key: HADOOP-132 > URL: http://issues.apache.org/jira/browse/HADOOP-132 > Project: Hadoop > Type: New Feature > Versions: 0.2 > Reporter: David Bowen > Fix For: 0.2 > Attachments: javadoc.tgz, javadoc.tgz, metrics.patch > > I'd like to propose adding an API for reporting performance metrics. I will > post some javadoc as soon as I figure out how to do so. The idea is for the > API to be sufficiently abstract that various different implementations can be > plugged in. In particular, there would be one that just writes the metric > data to a file, and another that sends metrics to Ganglia. It would also be > possible to plug in an implementation that can support high-frequency (say, > per-second) sending of fairly large amounts of data (up to hundreds of > metrics) across the network. > I'd be very interested in people's thoughts about what the requirements > should be for such an API. > - David Bowen -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
