Subject [jira] [Commented] (HIVE-15205) Create ReplDumpTask/ReplDumpWork for dumping out metadata
Date Tue, 15 Nov 2016 20:54:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-15205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15668286#comment-15668286

Vaibhav Gumashta commented on HIVE-15205:
-----------------------------------------

[~sershe] This jira doesn't touch ImportSemanticAnalyzer etc. It is resolving some of the
problems you are pointing to in original jira. All the classes here are new (unless you have
created ones with similar names).

> The current bootstrap code generates dump metadata during semantic analysis which breaks
security and task/work abstraction. It also uses existing classes (from Export/Import world)
for code reuse purpose, but as a result ends up dealing with a lot if-then-elses. It makes
sense to have a cleaner abstraction which uses ReplDumpTask and ReplDumpWork (to configure
the Task). Also perhaps worth evaluating ReplLoadTask/ReplLoadWork for load side.
