Sharad, thanks for taking a look. The test cases do pass for me (patch applied to revision e3d9a2bcbcab817043b1c4c41efb7036ce00904f).
Could you please post details of which tests are failing along with the trace and env.
The Data locality fix in this patch is a temporary patch to allow testing. A more efficient patch incorporating MR-2489 will be required later.
