>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 1.1.0
>            Reporter: Fan Yunbo
>            Assignee: Fan Yunbo
>             Fix For: 2.2.0

> See the query: 
> {code}
> create table if not exists DST as select * from SRC;
> {code}
> if the table DST doesn't exist, SessionState.get().getHiveOperation() will return HiveOperation.CREATETABLE_AS_SELECT;
> But if the table DST already exists, it will return HiveOperation.CREATETABLE;
> It really makes some trouble for those who judge operation type by SessionState.get().getHiveOperation().
> The reason I find out is that the function analyzeCreateTable in SemanticAnalyzer.java
will return null and won't set the correct command type if the table already exists.
> Here is the related code:
> {code}
> // check for existence of table
>     if (ifNotExists) {
>       try {
>         Table table = getTable(qualifiedTabName, false);
>         if (table != null) { // table exists
>           return null;
>         }
>       } catch (HiveException e) {
>         // should not occur since second parameter to getTableWithQN is false
>         throw new IllegalStateException("Unxpected Exception thrown: " + e.getMessage(),
e);
>       }
>     }
> {code}
