Howdy Ivan,

FYI, https://issues.apache.org/jira/browse/HADOOP-8545 is currently 
targeting 1.2.0 and 2.0.3-alpha. And the code (HADOOP-8545-034.patch) 
appears to provide support to Hadoop 1.x HDFS, though I may be missing 

I'd suggest only adding a Swift HCFS repo only if the code is not 
destined to go to Apache Hadoop.

+1 discuss at meeting
