Subject [3/3] git commit: BIGTOP-1342. Make TestCLI usable for both HDFS and HCFS
Date Sun, 13 Jul 2014 01:25:40 GMT
BIGTOP-1342. Make TestCLI usable for both HDFS and HCFS

This change splits TestCLI code into 2 parts:

 * TestCLI using testHCFSConf.xml (cases applicable for any Hadoop filesystem)
 * TestHDFSCLI using testHDFSConf.xml (HDFS only cases)
