      Description

      I used a reduced size covtype (10%) parsed to i.hex (r.hex)
      to make it go faster

      import_only: test_exec2_ddply_phrases.py uses local://home/kevin/home-0xdiag-datasets/standard/covtype.shuffled.10pct.data

      Path h2o will be told to use: /home/kevin/home-0xdiag-datasets/standard/covtype.shuffled.10pct.data

      parse parameters:

      {'header': None, 'destination_key': 'i.hex', 'separator': None, 'preview': None, 'exclude': None, 'header_from_file': None, 'parser_type': None, 'blocking': None, 'single_quotes': None, 'source_key': 'nfs://home/kevin/home-0xdiag-datasets/standard/covtype.shuffled.10pct.data'}

      exec_query parameters:

      {'str': 'r.hex=i.hex'}

      exec_query parameters: {'str': 'ddply(r.hex, c(2,3), function

      { cbind( mean(x[,1]), mean(x[,2]) ) })'}

      ERROR: got exception on http://192.168.0.37:54321/2/Exec2.json?str=ddply(r.hex, c(2,3), function { cbind( mean(x[,1]), mean(x[,2]) ) }

      ) to h2o.
