Examples with CreateDatabaseDesc org.apache.hadoop.hive.ql.ddl.database.create.CreateDatabaseDesc used on opensource projects

Example 1 with CreateDatabaseDesc

use of org.apache.hadoop.hive.ql.ddl.database.create.CreateDatabaseDesc in project hive by apache.

the class CreateDatabaseHook method authorizeDDLWork.

@Override
protected void authorizeDDLWork(HiveSemanticAnalyzerHookContext cntxt, Hive hive, DDLWork work) throws HiveException {
    DDLDesc ddlDesc = work.getDDLDesc();
    if (ddlDesc instanceof CreateDatabaseDesc) {
        CreateDatabaseDesc createDb = (CreateDatabaseDesc) ddlDesc;
        Database db = new Database(createDb.getName(), createDb.getComment(), createDb.getLocationUri(), createDb.getDatabaseProperties());
        authorize(db, Privilege.CREATE);
    }
}

Example 2 with CreateDatabaseDesc

use of org.apache.hadoop.hive.ql.ddl.database.create.CreateDatabaseDesc in project hive by apache.

the class LoadDatabase method createDbTask.

private Task<?> createDbTask(Database dbObj) throws MetaException {
    // note that we do not set location - for repl load, we want that auto-created.
    CreateDatabaseDesc createDbDesc = new CreateDatabaseDesc(dbObj.getName(), dbObj.getDescription(), getDbLocation(dbObj), getDbManagedLocation(dbObj), false, updateDbProps(dbObj, context.dumpDirectory));
    // If it exists, we want this to be an error condition. Repl Load is not intended to replace a
    // db.
    // TODO: we might revisit this in create-drop-recreate cases, needs some thinking on.
    DDLWork work = new DDLWork(new HashSet<>(), new HashSet<>(), createDbDesc, true, (new Path(context.dumpDirectory)).getParent().toString(), this.metricCollector);
    return TaskFactory.get(work, context.hiveConf);
}

Example 3 with CreateDatabaseDesc

use of org.apache.hadoop.hive.ql.ddl.database.create.CreateDatabaseDesc in project hive by apache.

the class CreateDatabaseHandler method handle.
