Takanobu Asanuma commented on HDFS-7687:
----------------------------------------
Thanks for your review, Nicholas!
bq. A Corrupt EC block group could have >= 6 blocks but some of the blocks are
corrupted.
bq. Yes, it is possible. E.g. a datanode D0 dies and a EC block in D0 is
reconstructed in another datanode D1. Later on, D0 comes back. Then, both D0
and D1 have the same EC block and the block group could have more than 9 blocks.
OK, I understand.
bq. For #1, see if you want to create a JIRA for trunk to do some refactoring
first.
You mean, if it needs to do some refactoring, we should do refactoring in trunk
branch first before we add the logic to handle EC?
