Steve Loughran commented on HADOOP-8161:
----------------------------------------

Regarding the org.apache.hadoop.fs.azurenative classes
# keys like {{"fs.azure.buffer.dir"}} need to be pulled out and made constants; 
the embedding of strings is something the main codebase is slowly moving away 
from. Some of the code does this, but not all.
# The code depends on microsoft-windowsazure-api 1.2.0 , which is in the maven 
repository. There's also a 0.2.0 version in there -any particular reason for 
not using the latest release?
# Testing? How is anyone working with this code going to use the FS? Is there 
S3-style remote access, or do you have to bring up a VM in the cluster?
# The catch of {{Exception}} and wrapping with {{AzureException}} is best set 
up so that {{IOException}} exceptions aren't caught and wrapped, as they match 
the signature. I don't know if the native API throws these, but adding an extra 
layer of nesting never helps with troubleshooting live systems.

It may be cleaner to keep the azure FS source tree outside the main hadoop 
code, and host it in a parallel hadoop-azurefs project with the extra 
dependency, and the extra output artifacts. Anyone who added a mvn or ivy 
dependency on hadoop-azurefs would get the -api JAR, and testing could be 
isolated. This could also be a good opportunity to do the same for KFS, which 
is under-tested in the current release process, and for any other DFS clients 
that people want in the codebase. Maybe the policy should be: if it is testable 
by anyone, put it in the hadoop source tree, but if not, the FS vendor has to 
do it. (I'm thinking of things like GPFS here and others, not just AzureFS)
