This difference causes some issues. > For instance, in {{HashTableSinkOperator#processOp}}, it uses a tag to look for information in various data structures, such as {{joinKeys}}, {{filterMaps}}, {{joinValues}}, etc. Those data structures stores the information BEFORE it splits the MJ operator with its parents. But, since later on we use separate {{HashTableSinkOperator}} for each small table, that information is no longer valid, and thus this method will fail. > This JIRA is to track and solve these related issues. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
