Zhe Zhang commented on HDFS-7165:
---------------------------------

[~andrew.wang] Thanks for the review. While I look into the ClientProtocol 
issue, here's a quite question:

bq. TestMissingBlocksAlert still has a whitespace-only change. Line 79-80 were 
deleted.

The original file has 2 empty lines there. In general, if we see formatting 
issues like that (indenting etc.), should we leave them there, correct them, or 
ask the original author to correct them?

> Separate block metrics for files with replication count 1

> We see a lot of escalations because someone has written teragen output with a 
> replication factor of 1, a DN goes down, and a bunch of missing blocks show 
> up. These are normally false positives, since teragen output is disposable, 
> and generally speaking, users should understand this is true for all repl=1 
> files.
> It'd be nice to be able to separate out these repl=1 missing blocks from 
> missing blocks with higher replication factors..
