-----------------------------------------
Summary: Some Query Options are not validated
Key: IMPALA-11537
URL: https://issues.apache.org/jira/browse/IMPALA-11537
Project: IMPALA
Issue Type: Bug
Reporter: Noemi Pap-Takacs
Query Options can be set in the Impala shell, but they are not validated
immediately.
Most Query Options require integer values. The input is parsed in
be/src/service/query-options.cc. There are many different solutions how these
integers are parsed. Some older implementations use atoi(), the newer ones
mostly use StringParser.
The older Query Options that use atoi() does not validate the input value,
which atoi() may not parse, so the query gets executed using the default value
for the given Query Option, without informing the user about it.
