Mingliang Liu commented on HDFS-11083:
--------------------------------------
{code}
537 fs.setReplication(file, (short) (replFactor + 1));
{code}
The replFactor is short type, isn't it?
{quote}
It addressed the 5 points though I didn't quite get #4.
{quote}
That was a bad format, I think you got the idea (using {{replFactor +1}}
instead of 2), as the above comment.

> {{hdfs dfsadmin -report}} has very useful information about the cluster.
> There are some existing customized tools that depend on this command
> functionality. We should add unit test for it. Specially,
> # If one datanode is dead, the report should indicate this
> # If one block is corrupt, the "Missing blocks:" field should report this
> # TBD...
