Hey friends,

I have been using Hive to explore my HDFS for a while now.

In my organization we have some applicative information in SqlServer that occasionally I need
to join with data I have in the HDFS.

When I need to do such a join, I import the data from the SqlServer using sqoop.

I wanted to know, if there is a way in which hive will import the data on demand, according
to the query, for example, if I am selecting from a table that hive recognizes as a SqlServer
table, it will import that table or(update if already exists) from sqlserver, and later will
run the select...
