[jira] [Created] (MADLIB-1160) Change term frequency indexes to start at 1 not 0

Frank McQuillan created MADLIB-1160:
---------------------------------------

             Summary: Change term frequency indexes to start at 1 not 0
                 Key: MADLIB-1160
                 URL: https://issues.apache.org/jira/browse/MADLIB-1160
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Utilities
            Reporter: Frank McQuillan
             Fix For: v2.0


Currently term frequency
http://madlib.apache.org/docs/latest/group__grp__text__utilities.html
creates indexes that start at 0 (e.g., docid)
whereas LDA
http://madlib.apache.org/docs/latest/group__grp__lda.html
creates indexes that start at 1 (e.g., topicid)

Since these are often used together, they should be consistent.  Recommend changing term frequency to start at 1.

Setting to 2.0 fix in case this is a breaking change for upgrading models.
