Does Hadoop 0.20.205 and Ganglia 3.1.7 compatible with each other ?

[quanta <qu...@gmail.com>]

Hi Varun Kapoor,

I've been trying to debug but unfortunately, I get the "No stack."
message from the gdb.
Here're the details:

  * Hadoop: 1.0
  * Ganglia: 3.1.7

    Program exited normally.


Wait for gmetad crash with following error in /var/log/messages:

    /usr/sbin/gmetad[6784]: *** buffer overflow detected ***:
    /usr/sbin/gmetad terminated


Go back to the (gdb) prompt:

    (gdb) bt
    No stack.
    (gdb) info locals
    No frame selected.


It sounds like gmetad catch the exception in the itself and (gdb) cannot
get any information.

I'll trying apply your patch for gmetad and let you know if it works.
