IMPALA-10140: Fix CatalogExeception for creating database with sync_ddl as true IMPALA-7961 handle the cases for query "create table if not exists" with sync_ddl as true. Customers reported similar issue which happened for query "create database if not exists" with sync_ddl as true. This patch adds the similar fixing as the fixing for IMPALA-7961 to function CatalogOpExecutor.createDatabase() to fix the issue. Testing: - Manual tests Since this is a racy bug, I could only reproduce it by forcing frequent topicUpdateLog GCs along with a specific sequence of actions, like: run some DDLs and REFRESHs to trigger a GC in topicUpdateLog, then run query "create database if not exists" with sync_ddl as true. Verified that the issue couldn't be reproduced after applying this patch. - Passed exhaustive test.
