I replicated the libsvm data from h2ostream that apparently didn't autodetect as libsvm.
just 5 lines.
If i don't say parser_type=SVMLight  it parses as enums (bad)
If I say parser_type=SVMLight, it gets this error in the parse json result:
rjson error in parse: Argument 'source_key' error: Parser setup appears to be broken, got SVMLight data with (estimated) 13 columns.

I looked at my other libsvm tests. Typically I don't specify parser_type=SVMLight
I wonder if those tests are parsing as enums now? but I thought I did some algos on them.

Maybe because the # of rows is small?

In any case, h2o is probably supposed to auto-detect as libsvm, and especially if I say parser_type=SVMLight it should parse it.

I didn't see anything wrong with the data. Col#s increment
I even stripped the multiple spaces in the separation
