Hi,
I am new to Hive. Just wanted a small clarification on the Float equality
comparison.
For instance, to check if A is equal to 3.5, is the usage of "A>3.49 and
A<3.51" in the WHERE clause of SELECT statement correct. Or do I have to
use the following:
"(NOT (A<3.5) AND NOT(A>3.5))"
What is the

Hi Folks,
Do the hadoop/hive remove the jobcache present on data node, or we can say

But you can put the data at same place and read through hive (actually no
need to insert data through table)
