Summary: Add a mapper to make plan transformations more easily understandable Key: HIVE-18564 URL: https://issues.apache.org/jira/browse/HIVE-18564 Project: Hive Issue Type: Improvement Reporter: Zoltan Haindrich Assignee: Zoltan Haindrich This part is started as a small helper class to enable plan independent mapping of runtime operator informations. But in reality its a bit different; and might have its own different kind of usages. Goals were: * connect plan pieces which are responsible for the same part together; currently I'm using it to connect RelNode, AST, Operator, RuntimeStats * make it easy to attach new data * make it easy to lookup some related information This concept seems to be also usefull during writing tests; because it enables the lookup of specific pieces like HiveFilter -- This message was sent by Atlassian JIRA (v7.6.3#76005)
