> Out of memory errors when number of records to import < 0.5 * splitSize
> -----------------------------------------------------------------------
>
> Key: SQOOP-1125
> URL: https://issues.apache.org/jira/browse/SQOOP-1125
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.4.3
> Reporter: Dave Kincaid
> Priority: Critical
>
> 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.
