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