Getting errors trying to generate the output file. Any help would be greatly
appreciated. Thanks
Index files are as follows:
_0.fdt
_0.fdx
_0.fnm
_0.frq
_0.nrm
_0.prx
_0.tii
_0.tis
segments.gen
segments_1
When I enter in this command I get the following errors:
$mahout org.apache.mahout.utils.vectors.lucene.Driver --dir
/home/temp/text_output --output /home/temp/text_output --dictOut
/home/temp/text_output --max 50 --field contents
