Phoenix CSV Bulk Load fails to load a large file

[Sriram Nookala]

I'm trying to load a 3.5G file with 60 million rows using CsvBulkLoadTool.
It hangs while loading HFiles. This runs successfully if I split this into
2 files, but I'd like to avoid doing that. This is on Amazon EMR, is this
an issue due to disk space or memory. I have a single master and 2 region
server configuration with 16 GB memory on each node.
