| We are doing a project in Hive.
| Given a field / value  is it possible to find the corresponding
| headers (meta data).
| 
| For example if we have a table with id, user, work_place,
| residence_place
| 
| given a value "New York" we need to display the headers where New
| York appears ( for eg work_place, residence_place etc.
| 
| Kindly intimate whether  it is possible. If so what is the command
| for the same?
| Thanking you

| Hi Sudha
| 
| Good question.
| 
| First of all, you need to specify clearly about your Hadoop
| environment,
| (pseudo distributed or real cluster)
| 
| Secondly, you need to clearly understand how hadoop load job's jar
| file to
| all worker nodes, it only copy the jar file to worker nodes. It does
| not
| contain the jcuda.jar file. MapReduce program may not know where it
| is even
| you specify the jcuda.jar file in our worker node classpath.
| 
| I prefer you can include the Jcuda.jar into your wordcount.jar. Then
| when
| Hadoop copy the wordcount.jar file to all worker nodes' temporary
| working
| directory, you do not need to worry about this issue.
| 
| Let me know if you meet further question.

Kindly provide us with website address for tutorials on JCUDA + hadoop with steps for execution
