    Hi,
    Most of our map jobs are IO bound. However, for the same node, the IO throughput during the map phase is only 20% of its real sequential IO capability (we tested the sequential IO throughput by iozone)
    I think the reason is that while each map has a sequential IO request, since there are many maps concurrently running on the same node, this causes quite expensive IO switches.
    Prefetch may be a good solution here especially a map job is supposed to scan through an entire block and no more no less. Any idea how to enable it?

    Thanks,
    -Songting

    Rajshekar,
    It seems that your namenode isn't able to load FsImage file.

    Here is a thread about a similar issue:

    Rajshekar,
    I have also threads for this ;)

    http://mail-archives.apache.org/mod_mbox/hadoop-core-user/200803.mbox/%3CPine.LNX.4.64.0803132200480.5549@localhost.localdomain%3E
    http://www.mail-archive.com/hadoop-dev@lucene.apache.org/msg03226.html

    Please try the following:

    - Give local filepath for jar
    - Give absolute path, not relative to the hadoop/bin
    - HADOOP_HOME env. variable should be correctly set.

    Hope this helps,
    Rasit
