variable to be assigned with an atomic value from a query
---------------------------------------------------------
Key: HIVE-2165
URL: https://issues.apache.org/jira/browse/HIVE-2165
Project: Hive
Issue Type: Sub-task
Reporter: Ning Zhang
Currently variable can only be assigned by a constant. There are cases where a
query generate a single value that should be used by the second query. It would
be nice to assign this value to a variable and pass it to the second query. For
exmaple:
{code}
hive> set x_avg = `select avg(x) from T`;
hive> select my_udf(${hiveconf:x_avg}, y) from T2;
{code}
