Summary: lucene2seq creates single document from index
Key: MAHOUT-1292
URL: https://issues.apache.org/jira/browse/MAHOUT-1292
Project: Mahout
Issue Type: Bug
Components: Integration
Affects Versions: 0.8
Reporter: Liz Merkhofer
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.
