Hi all!
Can someone please briefly explain the difference? I do not see
deprecated warnings for fs.local.block.size when I run with them set and
I see two copies of RawLocalFileSystem.java (the other is
local/RawLocalFs.java).
The things I really need to get answers to are:
1. Is the default boosted to 64MB from Hadoop 1.0 to Hadoop 2.0? I
believe it is, but want validation on that.
2. Which one controls shuffle block-size?
3. If I have a single machine non-distributed instance, and point it at
file://, do both of these control the persistent data's block size or
just one of them or what?
4. Is there any way to run with say a 512MB blocksize for the persistent
data and the default 64MB blocksize for the shuffled data?
Thanks!
