[jira] [Work logged] (HIVE-24249) Create View fails if a
materialized view exists with the same query
[ https://issues.apache.org/jira/browse/HIVE-24249?focusedWorklogId=515531&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-515531 ]

Work Description: kasakrisz opened a new pull request #1696:
URL: https://github.com/apache/hive/pull/1696
### What changes were proposed in this pull request?
Disable materialized view rewrite at view creation.
### Why are the changes needed?
Hive doesn't support view creation when one of the source tables is a materialized view. When the `create view` command is executed the select statement is compiled and the optimizer applies materialized view rewrites if any suitable materialized view exists. A successful rewrite leads to Exception:
```
org.apache.hadoop.hive.ql.parse.SemanticException: View definition references materialized view default.mv1
```
See the jira for full stacktrace.
### Does this PR introduce _any_ user-facing change?
Users can create views even if its query is matching with an existing materialized view query. No SemanticException should be thrown because of that.
### How was this patch tested?
```
mvn test -Dtest.output.overwrite -DskipSparkTests -Dtest=TestMiniLlapLocalCliDriver -Dqfile=create_view_when_mv_exists.q -pl itests/qtest -Pitests
```
