我在具有分区的配置单元中创建了一个外部表，然后尝试从现有表填充它，但是，出现以下异常：

根据互联网，当datanode无法与namenode通信或内存不足时，就会出现这些异常，但在我的情况下，一切正常。我已经尝试格式化我的namenode和datanode了。还有什么问题？
https://wiki.apache.org/hadoop/couldonlybereplicatedto 我也读过这个。但这对我毫无帮助。
我在找泰兹。这样做有效： insert into table browserdatapart partition(cityid) select UserAgent,cityid from browserdata limit 100; 但我提供了一个例外：

insert into table browserdatapart partition(cityid) select UserAgent,cityid from browserdata;
