Richard Ding commented on PIG-1454: ----------------------------------- I've run the core tests manually and they passed. > Consider clean up backend code > ------------------------------ > > Key: PIG-1454 > URL: https://issues.apache.org/jira/browse/PIG-1454 > Project: Pig > Issue Type: Improvement > Components: impl > Affects Versions: 0.7.0 > Reporter: Richard Ding > Assignee: Richard Ding > Fix For: 0.8.0 > > Attachments: PIG-1454.patch > > > Prior to 0.7, Pig had its own local execution mode, in addition to hadoop map > reduce execution mode. To support these two different execution modes, Pig > implemented an abstraction layer with a set of interfaces and abstract > classes. Pig 0.7 replaced the local mode with hadoop local mode and made > this abstraction layer redundant. > Our goal is to remove those extra code. But we need also keep code backward > compatible since some interfaces are exposed by top-level API. > So we propose the first steps: > * Deprecate methods on FileLocalizer that have DataStorage as parameter. > * Remove ExecPhysicalOperator, ExecPhysicalPlan, ExecScopedLogicalOperator, > ExecutionEngine and util/ExecTools from > org.apache.pig.backend.executionengine package. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
