Description Daniel Horák 2013-10-17 08:34:37 UTC 
Description of problem:
  Actual version of shim (now 2.1.4) logs only few lines about shim version and no other (debugging) information and records. It would be good to have possibility to get more information about running actions.

One example is debugging problem with getfattr (see bug 1002020) - executed Hadoop (mapreduce) job fails with general "Cannot get layout" exception and it is not clear what is the problem.
> It happens when xtended attrs arent available either:
> 1) Because user running task or job doesnt have sudo privileges and your hadoop config (core-site.xml) sets the getfattr command to use sudo.  
> 2) Your gluster mount is severely broken, or not mounted at all.
> 3) You are running without a TTY (i.e. this happens when jenkins launches our jobs - even if it is root - so you have to disable tty in sudoers - yes even for root!) 
> 4) If /usr/bin/getfattr isnt installed (in a fedora19 distro, i found i had to manually install it: yum install     yum install attr)

Version-Release number of selected component (if applicable):
  glusterfs-hadoop-2.1.4.jar
Comment 2 Jay Vyas 2013-11-19 13:21:12 UTC 
Agreed that we (1) need a revised logging patch + (2) instructions on the 
forge.gluster.org about how to debug the shim and capture/ configure logs.
Comment 3 Scott Haines 2013-11-19 19:58:03 UTC 
Per 11/13 bug triage meeting, re-assigning to bchilds and mark medium.

gluster-hadoop project is not being actively maintained, and the team is not planning to contribute further on to it.
