Subject [jira] [Commented] (HDFS-7613) Block placement policy for erasure coding groups
Date Thu, 12 Feb 2015 02:21:12 GMT

Jing Zhao commented on HDFS-7613:
---------------------------------

Thanks for sharing the thoughts, [~walter.k.su]! I think we should start from the 2nd policy
since in our first phase we only do RS and striped blocks. Each block contained in a block
group (or BlockInfoStriped in the current code) only has one replica.

> Blocks in an erasure coding group should be placed in different failure domains -- different
DataNodes at the minimum, and different racks ideally.
