Subject [jira] [Updated] (MAHOUT-1150) ARFF Integeration does not support quoted identifiers
Date Wed, 27 Feb 2013 21:39:13 GMT

     [ https://issues.apache.org/jira/browse/MAHOUT-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Marty Kube updated MAHOUT-1150:
-------------------------------

    Description: 
I ran NSL-KDD data set (http://nsl.cs.unb.ca/NSL-KDD/) through the ARFF integration.  The
process failed to parse the arff formatted file.  The file has quoted identifiers:

@relation 'KDDTrain-20Percent'
@attribute 'duration' real
@attribute 'protocol_type' {'tcp','udp', 'icmp'} 

The quotes caused the problem.  The "official" arff BNF shows that quotes should be supported:
