Daryn Sharp updated HDFS-2450:
------------------------------
Attachment: HDFS-2450-2.patch
Optimized {{NetUtils.getCanonicalUri()}} to return same uri in majority of
cases. DNS canonical resolutions are cached to accelerate the method when
use_ip=false.
Optimized {{FileSystem.checkPath()}} to avoid redundant code. I tried to keep
it as similar as possible to simplify review. Although I was itching to change
it to stop creating locals that won't be used in some cases, or that will be
used only once, etc.
{{DistributedFileSystem}} manages its uri like the other filesystems. By not
manipulating the given uri, the removed methods are not needed to compensate
for the previous manipulations.
Tests appear to be passing. Running full test suite overnight.
> Only complete hostname is supported to access data via hdfs://
