Hello MapR community,

I am running a 4 node test M5 cluster, latest version of MapR on RHEL 6.2.  When running a test mapr reduce using teragen/terasort, the cluster completes the teragen OK.  It fails when running the terasort job. The system generates a lot of diag messages.  It seems as though the root of the cause (as reported in stderr log for the job) is as follows:

I'm hoping there is some simple/fundamental config error that is causing this.  Any ideas?

Thanks - Chris
