Thanks yongqiang he.
Is there any alternative method to do data (type) validation in Hive?

Right now Hive does not do data validation when loading data into a table.
If you load some wrong data which does not conform the table
definition, queries on that table may fail or results are meaningless.

Dear Hive Community,
I've been trying to see if Hive (0.5.0) supports data type validation when
loading data into it. My initial experiments show me that if it is of wrong
data type (vs the table definition), the values seem to be NULL. Is it
correct?
Can anyone point to useful resources with respect to this?
