greenplum 启用gpfdist后无效，测试下载400错误

Question

1.GP软件4.3.15,系统centos6.9
2.在master测试gpfdist启用外部表功能
3.$ gpfdist -d /data/loderfile/ -p 8080 -l /home/gpadmin/log &
4.

开启正常

5.使用WGET 下载文件测试报错
[gpadmin@mdw ~]$ wget http://mdw:8080/aaa
--2017-07-26 07:07:06-- http://mdw:8080/aaa
Resolving mdw... 10.0.0.121

HTTP request sent, awaiting response... 400 invalid request (no gp-proto)
2017-07-26 07:07:06 ERROR 400: invalid request (no gp-proto).

6.查看日志

求解这是怎么回事？？

Answer 1

您好，请问下你的greenplum是在官网上下载的吗?我为什么注册后，在官网上无法下载呢？

Answer 2

你用的是gpfdist启动的服务；用wget http://IP:PORT当然有问题
如果用http协议启动，那么访问文件是没问题的

这个不影响你的外部表的使用
