Hi Ni‎shant,

It looks like there is no enough memory to hold the data. How much aggregate memory available in your cluster? 

Thanks,

Hi All,

I am running Giraph job with around 250 MB of compressed data. I am using EMR with one master and two data nodes. My input directory contain 18 files.

If I launch 18 jobs for all files separately it works fine. I am not doing any computation. In first super step itself all vertex vote for halt.

I am not getting any error. Job keep running for hours and does not produce anything. 

Appreciate any help.

Thanks,
Nishant
