-------------------------------------------

Looks good [~SaiKarthik]. Could you please merge both patch into single file, remove trailing
whitespaces and upload it here? Also be careful when generating the final patch - the latest
attached file doesn't seem to be fully valid:

{code}
jarcec@arlene sqoop % git apply SQOOP-1125.patch
SQOOP-1125.patch:17: trailing whitespace.

SQOOP-1125.patch:27: trailing whitespace.

SQOOP-1125.patch:48: trailing whitespace.

SQOOP-1125.patch:50: trailing whitespace.

fatal: corrupt patch at line 53

> We are getting out of memory errors during import if the number of records to import
is less than 0.5*splitSize (and is nonterminating decimal).
> For example, if the numSplits = 3, minVal = 100, maxVal = 101 then in BigDecimalSplitter.split()
an extraordinary number of tiny values will be added to the splits List and run out of memory
eventually.
> I also noticed that there are no tests for BigDecimalSplitter.
