> Lucene2seq creates only one sequencefile, rather than a file for each
> document in the index.
> Running lucene2seq on my Solr (4.3) index produces a file with a header and,
> it seems, the field I specified from the index, concatenated for all the
> documents. After running this through seq2sparse and rowid (to prepare for
> cvb), the resulting matrix has only one row, though it should create one row
> per document.
> This issue prevents, at least, data from a lucene index from being easily
> used as input for cvb. Lucene.vector is also currently inadequate: the keys
> to its sequence files are LongWriteable, and rowid will not convert only Text
> to IntWriteable, as is necessary for the keys in cvb.
