Zoltan Haindrich reassigned HIVE-18564: --------------------------------------- > 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 > Priority: Major > > 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)
