Ok I have already set up mine
<property>
<name>hive.limit.optimize.fetch.max</name>
<value>50000</value>
<description>
Maximum number of rows allowed for a smaller subset of data for
simple LIMIT, if it is a fetch query.
Insert queries are not restricted by this limit.
</description>
</property>
I am surprised that yours was missing. What did you set it up to?
