Does HDFSIO load .smat file from HDFS directly?

[junshi15]

Similar to mat = HMat.loadMat("/tmp/A.smat"), if "/tmp/A.smat" is located in HDFS, can we load it directly? i.e. something like mat = hdfsio.readMat("hdfs:///myhostname/tmp/A.smat").
From the code, readMat/Mats only read from sequencefiles, not .xmat directly. Am I right?
