[jira] [Updated] (MAHOUT-403) Regex to Various Output Formats
[ https://issues.apache.org/jira/browse/MAHOUT-403?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Grant Ingersoll updated MAHOUT-403:
-----------------------------------
Attachment: MAHOUT-403.patch
Up to date with trunk, adds test. I used this to convert a bunch of Solr log files to FPG format.
I think it will work fairly well for single line files. It is more flexible than Hadoop's built in RegexMapper, AFAICT.

> Would be great to have a M/R job that took in a line, applied a regex to it and then used the capturing groups as output to various formats (FPG, Classifier, etc.)
