> In AMBARI-22600, we cloned the Filter instance to assign the instance per child thread,
which also clones the map of Mapper. Other Mapper implements only have String(s) type of fields
hence thread-safe, but MapperDate has SimpleDateFormat type of fields which is known as non
thread-safe, so cloning the Filter which has one or more MapperDate and using them concurrently
makes multi-threads issue.
> For example I'm seeing the logdate improperly stored.
