建表的时候报错，报错信息： failed to create partition.Timeout。
1.建表语句：
CREATE TABLE table1
(
siteid INT DEFAULT '10',
citycode SMALLINT,
username VARCHAR(32) DEFAULT '',
pv BIGINT SUM DEFAULT '0'
)
AGGREGATE KEY(siteid, citycode, username)
DISTRIBUTED BY HASH(siteid) BUCKETS 10
PROPERTIES("replication_num" = "1");

2.backends信息：

5. 在trash的文件夹里可以看到有dat文件里有表结构信息，所以跟日志一致，be表是创建成功的
