Kai Zheng updated HADOOP-12011:
-------------------------------
    Attachment: HADOOP-12011-HDFS-7285-v3.patch

Thanks Uma for the good comments! Updated the patch accordingly.
Also moved the utilities into the rawcoder package because they're needed there to dump data
in the concrete processing during coding/decoding in native coders.

> While working on native erasure coders, it was found useful to dump key information like
encode/decode matrix, erasures and etc. for the encode/decode call.
