Dave Beech reassigned MRUNIT-154:
---------------------------------
Assignee: Dave Beech
> shuffle in MapReduceDriverBase does not support comparators that only
> override compare(byte[] b1, int s1, int l1, byte[] b2, int s2, int l2)

> Key: MRUNIT-154
> URL: https://issues.apache.org/jira/browse/MRUNIT-154
> Project: MRUnit
> Issue Type: Bug
> Reporter: Jim Donofrio
> Assignee: Dave Beech
>
> From MRUNIT-114:
> Because the shuffle method in MapReduceDriverBase calls the key ordering
> comparator using compare(Object,Object), it does not call the correct method
> on classes which only override and do all the work in compare(byte[] b1, int
> s1, int l1, byte[] b2, int s2, int l2), like KeyFieldBasedComparator.
> It might be better to check whether the two keys are BinaryComparable,
> casting, and calling this method if possible. Even if a user's comparator
> doesn't override it, the default implementation of this in WritableComparator
> would still be OK.
