Subject [jira] [Commented] (HDFS-7716) Erasure Coding: extend BlockInfo to handle EC info
Date Sat, 07 Feb 2015 00:59:35 GMT

Zhe Zhang commented on HDFS-7716:
---------------------------------

bq. Actually I do not think we need that sanity check since the current code already does
the conversion before the check.
Right.. Strange why this assert was added.

> The current BlockInfo's implementation only supports the replication mechanism. To use
the same blocksMap handling block group and its data/parity blocks, we need to define a new
BlockGroupInfo class.
