Review request for hive, Ashutosh Chauhan and Jesús Camacho Rodríguez.
Bugs: HIVE-18163
https://issues.apache.org/jira/browse/HIVE-18163
Repository: hive-git
Description
-------
* collect stats for {{create materialized view}} as well; AFAIK its not
possible to do an update on a materialized view ; so every materialized view
operation can be considered as a rewrite w.r.t stats
* added a small collection to delay the construction of the view objects in
`MaterializedViewRegistry`; the reason this was needed is:
* `StatsTask` runs after `DDLTask` :
* `DDLTask` invoked `MaterializedViewRegistry` to put the view in
cache
* `StatsTask` filled out the basicStats info in the metastore...
* next query used the *out-dated* cached table object (which was
available at the time {{MaterializedViewRegistry}} built the scanner.
* I've rerun all the "materialized_view" tests. and the results look good to me
* in materialized_view_create_rewrite_2.q.out the usage of {{cmv_mat_view_5}}
appeared; which looks good to me
