Aaron T. Myers commented on HDFS-1900:
--------------------------------------
Thanks a lot for checking on that, Abel. That seems fine to change.
The patch application failed with the following error "Looks like this is a
cross-subproject patch. Not supported!"
This happened because this change affects both the Common and HDFS subprojects.
Unfortunately, the QA bot can't presently handle this, so you'll need to run
test-patch yourself and paste the output here as a comment.
Sorry about that. :/

> HADOOP-4952 added a dfs.block.size key to common configuration, defined in
> o.a.h.fs.FsConfig. This conflicts with the original HDFS block size key of
> the same name, which is now deprecated in favor of dfs.blocksize. It doesn't
> make sense to have two different keys for the block size (ie they can
> disagree). Why doesn't HDFS just use the key defined in common?
