new OlapTableSink without any partition may cause IllegalStateException

[xinghuayu007]

Describe the bug
In LoadingTaskPlanner#Plan(): OlapTableSink olapTableSink = new OlapTableSink(table, tupleDesc, partitionIds); If the table does not has any partition, Preconditions.checkState will throw IllegalStateException, but the funtion only cath UserException, that will cause load job status can not be updated。

To Reproduce
Steps to reproduce the behavior:

1. create a table without partition:
   CREATE TABLE table1
   (
   event_day DATE,
   siteid INT DEFAULT '10',
   citycode SMALLINT,
   username VARCHAR(32) DEFAULT '',
   pv BIGINT SUM DEFAULT '0'
   )
   AGGREGATE KEY(event_day, siteid, citycode, username)
   PARTITION BY RANGE(event_day)()
   DISTRIBUTED BY HASH(siteid) BUCKETS 10
   PROPERTIES("replication_num" = "1");

2. broker load job:
   LOAD LABEL db1.label1
   (
   DATA INFILE("hdfs://abc.com:8888/user/palo/test/ml/file1")
   INTO TABLE tbl1
   COLUMNS TERMINATED BY ","
   (event_date,siteid,citycode,username,pv)
   SET
   (
   date=event_date,
   id=siteid,
   code=citycode,
   name=username
   count=pv
   ),
   )
   WITH BROKER 'broker'
   (
   "username"="user",
   "password"="pass"
   )
   PROPERTIES
   (
   "timeout" = "3600"
   );

3. error log:
   

4. job status not be updated
