Variable support in Amazon's Elastic MapReduce version of Hive
Vijay 2009-12-20, 02:29
Amazon Elastic MapReduce version of Hive seems to have a nice feature called
"Variables." Basically you can define a variable via command-line while
invoking hive with -d DT=2009-12-09 and then refer to the variable via ${DT}
within the hive queries. This could be extremely useful. I can't seem to
find this feature even on trunk. Is this feature currently anywhere in the
roadmap?
