Subject Hive documentation update for isNull, isNotNull etc.
Date Fri, 17 Apr 2015 21:22:03 GMT
I'm having major trouble finding documentation on hive functions isNull and isNotNull.
At first I was assuming the function just wasn't available, now I believe these functions
are not documented.

I believe that the LanguageManual+UDF#LanguageManualUDF-Built-inFunctions<https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-Built-inFunctions>
is the right wiki page:

Interestingly, I found a HIVE-521 (resolved in 0.4) to be the first reference for isNull within
JIRA.

Is Lefty volunteering for this? If not I can make the edits if given permissions.

Thanks
Douglas
