What's Wrong?

Unable to export empty data to hdfs / S3, this behavior is inconsistent with version 1.2.7, version 1.2.7 can export empty data to hdfs/ S3, and there will be exported files on S3/HDFS.

Here is the behavior on version 2.0.4:

1. If export empty data to s3, it will return success, but there are no exported files on S3.
   Reproduction method:

select * from test_tb where id=0 INTO OUTFILE  "s3://repo/test-outfile-empty/my_file_"
properties (
    "AWS_ENDPOINT" = "xxx",
    "AWS_ACCESS_KEY" = "xxx",
    "AWS_SECRET_KEY"="xxx",
    "AWS_REGION" = "bj"
)

2. if export empty data to hdfs use broker, it will return failed because not open broker writer but close it.(if not use broker the behavior is same as export file to s3, exported files not exist)
   Reproduction method:

select * from test_tb where id = 0 INTO OUTFILE "hdfs://host:port/data/export/empty/label_23_20_48_26_453655_1336993759/label_23_20_48_26_453748_1090390474"  PROPERTIES ( "broker.fs.defaultFS" = "hdfs://host:port","broker.name"="hdfs","broker.username"="user","broker.password"="password");
