bq. [giant table of configuration]
I'm not too excited about the giant table of configuration. It seems to
duplicate what we have in {{hdfs-defaults.xml}}. We already have the problem
of the configuration keys being duplicated between {{DFSConfigKeys.java}} and
{{hdfs-defaults.xml}}; adding a third duplicated area seems suboptimal.
Additionally, most users will never have to configure anything related to
HDFS-5810. I think maybe we should just add a sentence or two about the shared
memory segments, but certainly not describe every possible thing that you could
conceivably configure. Remember, this is an introduction to SCR.

Colin Patrick McCabe commented on HDFS-6007:
Thanks for looking at this. I think we should limit the scope here to just
adding a sentence about shared-memory segments, and adding some documentation
about the legacy short-circuit implementation.
I think the zero-copy API should get its own document. Putting it in here just
seems like information overload.
{code}
+ Client and DataNode uses shared memory segments
+ to communicate short-circuit read.
{code}
How about "The client and the DataNode exchange information via a shared memory
segment."
{code}
+ if /dev/shm is not world writable or does not exist in your environment,
+ You can change the paths on which shared memory segments are created by
+ setting the value of <<>>
+ to comma separated paths like <<>>.
+ It tries paths in order until creation of shared memory segment succeeds.
{code}
Can we skip this section? 99.999% of users will never need to change that
config value, and there's documentation in hdfs-defaults.xml for those who do.
The number of UNIX systems without /tmp must be pretty small indeed.
{code}
+ Legacy short-circuit local reads implementation
+ on which clients directly open HDFS block files is still available
+ for platforms other than Linux.
{code}
Missing 'the'
I think we need a sentence or two explaining that the old short-circuit
implementation is insecure, because it allows users to directly access the
blocks. We also need some explanation about how you have to chmod the blocks
into the correct UNIX group so that they are accessible.
Please skip the configuration tables. They just duplicate hdfs-default.xml

I think this section needs to be moved after the section about
dfs.datanode.data.dir.perm. Otherwise it's not clear why the legacy SCR is
insecure.
