Andrew Wang commented on HDFS-8697:
-----------------------------------
Hi Zhe, thanks for working on this, a couple review comments:
* "stored block" has a meaning elsewhere in the code base, we should use a
different term. Not sure what though. Sufficiently redundant? Sufficiently
durable?
* Many log messages and comments still talk about replication.
* Explaining the expectations of decomming a DN with EC blocks somewhere would
be good too. Do we treat them like 1-repl blocks? Or allow a block to dip below
full-strength redundancy? It seems like the former (which I agree with), but
should write this down somewhere.
