Íñigo Goiri commented on HDFS-12923:
------------------------------------

[~eddyxu], could you elaborate on why is not an issue?

> DFS.concat should throw exception if files have different EC policies.

> {{DFS#concat}} appends blocks from different files to a single file. However, 
> if these files have different EC policies, or mixed with replicated and EC 
> files, the resulted file would be problematic to read, because the EC codec 
> is defined in INode instead of in a block.
