Spark 使用GSC 連接Gp 寫入數(shù)據(jù)時(shí)候報(bào)錯(cuò)：

PSQLException: ERROR: permission denied: no privilege to create a readable gpfdist(s) external table

錯(cuò)誤原因：當(dāng)前用戶沒有權(quán)限創(chuàng)建外部表

完整錯(cuò)誤如下：

解決方式：登陸gpmaster 節(jié)點(diǎn)，切換到gpadmin用戶，執(zhí)行修改權(quán)限的操作，修改完成之后需要flush才能生效

下面的user 替換為操作gp的用戶名 cdp=# alter role user CREATEEXTTABLE; ALTER ROLE cdp=# flush
