报错：
ERROR 1064 (HY000): Unexpected exception: Table replication num should be less than of equal to the number of available BE nodes. You can change this default by setting the replication_num table properties. Current alive backend is [10002]. table=detailDemo, default_replication_num=3

default_replication_num
含义：用于配置分区默认的副本数。如果建表时指定了 replication_num 属性，则该属性优先生效；如果建表时未指定 replication_num，则配置的 default_replication_num 生效。建议该参数的取值不要超过集群内 BE 节点数。
默认值：3

解决：
建表语句最后加上：
PROPERTIES(
    "replication_num" = "1"
);
