我执行上面显示的简单pig脚本，它使用秩操作符和并集。它抛出：error 2017:internal error creating job configuration。
A = LOAD '/location/to/my/file';
SPLIT A INTO
B IF $0 IS NULL,
C IF $0 IS NOT NULL;
B2 = RANK B;
C2 = RANK C;
D = UNION B2, C2;
STORE D INTO '/location/to/my/outputs/1';有人知道怎么解决这个问题吗？
完整的错误日志是：

这个问题已经在上面的链接中展开：https://issues.apache.org/jira/browse/pig-3985
它似乎在pig版本0.14.0上得到了解决
不幸的是，我正在开发0.12pig版本，它需要一个特定的补丁来修复cloudera的问题。

这会有用的。。只要写一个foreach后，你申请职级，然后联合的关系
