Zheng Shao commented on HIVE-236:
---------------------------------
@HIVE-236.2.patch:
The warning should not be outputted for every call - we had seen problems with too many repeated
log messages that filled up the log file.
Can you add a boolean variable "warned", so that we only warn once?
Also, it may help if you put all the test cases in a single query. That helps to reduce the
time of running tests.
> RLIKE/REGEXP should allow matching partial strings

> The current behavior is that the regexp needs to match the whole string.
> But from mysql: ( http://dev.mysql.com/doc/refman/5.0/en/regexp.html#operator_regexp
)
> mysql> SELECT 'fofo' REGEXP '^fo'; -> 1
> We need to make it work the same way as MySQL.
