---------------------------------
[~mithun] Sorry for the late reply. Busy with something else. Seems it's hadoop
version related issue.
Would it be fair to update all the calls in HCatalog to use the new
getInstance() since it's deprecated anyway? If you agree, I will use this jira
to do that and I will update the title to reflect it.
> Pig+Hcatalog doesn't work properly since we need to clone the Job instance in
> HCatLoader

> The expected result is (1,111,333,1,2) while the result is (1,2,333,1,2). We
> need to clone the job instance in HCatLoader.
