Subject hive map field question
Date Wed, 23 Nov 2011 15:48:07 GMT
Hello HiveUsers,

I have a need to convert a map<string,string> field to string field and vice versa in
a hive table.  I could not do cast.

I created two external tables with one has string and another map.  I can join both to get
what I want, takes a long time.

Any ideas of how it can be done efficiently ?
