Hi all,
Have you seen this problem ever? Please help me , thanks very much!
By the way, it works well with single server, when I deploy hadoop using mesos
scheduler on 3 servers, the problem occures.

randomwriter -Dtest.randomwrite.bytes_per_map=6710886
-Dtest.randomwriter.maps_per_host=10 rand
Running 30 maps.
