For this to work, do I need Spark with Scala 2.11 support? The available spark binaries are built with scala 2.10 at this moment.

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?
I have the suggested AMI up and running with BIDMach. Cloned this repo into it but do not know: (a) where is HADOOP_HOME and (b) getting lots of compilation errors

Where does this BIDMat.SerText class come from?
I can't find reference to it any where in the BIDMat repo.
error: object SerText is not a member of package BIDMat

I would like to create a small PR with a small Test and/or example. Some suggested code to use for these would be appreciated.
Otherwise I will be attempting to reverse engineer from the API's and put together something.
