Otis Gospodnetic commented on HADOOP-3585:
------------------------------------------
Curious observer's comment to the following statement:
"FailMon is now a contrib project and its code is decoupled from the Hadoop
core."
Would it then make sense to package and publish this separately? Publishing it
in Hadoop's contrib may hide it from those who could use failure monitoring
outside Hadoop, but do not know to look for this gem in Hadoop's contrib.

> At IBM we're interested in identifying hardware failures on large clusters
> running Hadoop/HDFS. We are working on a framework that will enable nodes to
> identify failures on their hardware using the Hadoop log, the system log and
> various OS hardware diagnosing utilities. The implementation details are not
> very clear, but you can see a draft of our design in the attached document.
> We are pretty interested in Hadoop and system logs from failed machines, so
> if you are in possession of such, you are very welcome to contribute them;
> they would be of great value for hardware failure diagnosing.
> Some details about our design can be found in the attached document
> failmon.doc. More details will follow in a later post.
