      Description

      Refering to the documentation (https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties), it is possible to set the following property "hive.mapjoin.optimized.keys". Unfortunately, this property seems to be unknown to Hive.
      Here is an extract of the hive-site.xml which includes the property:

        <property>
            <name>hive.mapjoin.optimized.hashtable</name>
            <value>true</value>
            <description>Whether Hive should use a memory-optimized hash table for MapJoin. Only works on Tez, because memory-optimized hash table cannot be serialized.</description>
        </property>
      

      In the logs I have:

      May 24 09:09:02 hiveserver2.bigdata.fr HiveConf of name hive.mapjoin.optimized.keys does not exist
