Subject Re: Help with tuning for larger clusters

Hi, Joe, from the config you have sent to Denis it is seen that (1) you use
shmem to communicate to IGFS; (2) you have secondary file system enabled
So, the suggestions to investigate the problem are: 
1) try to perform the same experiment with primary IGFS filesyetem only
(<property name="defaultMode" value="PRIMARY"/>, + comment out the secondary
file system section). 
2) try to communicate with IGFS with TCP protocol (<property name="type"
value="TCP" />). Shmem requires shmem library (ignite-shmem-1.0.0.jar) to be
present in hadoop client classpath. Also it requires the client to be run on
the machine where at least one cluster node is running.
Is the same problem also observed with these changes?
