Sahil Takiar updated IMPALA-7777:
---------------------------------
Description: A follow up to IMPALA-5004. Impala allows a value of LIMIT and
OFFSET up to Java's {{Long.MAX_VALUE}}. However, if a user tries to run a query
with a large offset (even 2^32, the query will crash the impalad due to a
{{DCHECK_LE}}. (was: A follow up to IMPALA-5004. We should prevent users from
running queries where the sum of the offset and limit exceeds some threshold
(e.g. {{Long.MAX_VALUE}}). If a user tries to run this query the impalad will
crash, so we should reject queries that exceed the threshold.)
