Thanks [~wilfreds], moving this to 2.6.4.

> This is the follow up for MAPREDUCE-6549. Compressed files cause record
> duplications as shown in different junit tests. The number of duplicated
> records changes with the splitsize:
> Unexpected number of records in split (splitsize = 10)
> Expected: 41051
> Actual: 45062
> Unexpected number of records in split (splitsize = 100000)
> Expected: 41051
> Actual: 41052
> Test passes with splitsize = 147445 which is the compressed file length.The
> file is a bzip2 file with 100k blocks and a total of 11 blocks
