hadoop - 如何在 oozie 中将 pig 选项作为参数传递？

Question

为了执行我的 pig 脚本，我需要关闭优化器。在命令行和脚本中使用以下命令可以正常工作。

 pig -t ColumnMapKeyPrune population.pig

如何在oozie中传递这个选项？

我试过作为参数传递。

<action>
<pig>
    <job-tracker>${jobTracker}</job-tracker>
    <name-node>${nameNode}</name-node>                      
    <script>Population.pig</script> 
    <argument>-t</argument>
    <argument>ColumnMapKeyPrune</argument>
    <param>piggybankJar=${piggybankJar}</param>
    <param>datafuJar=${datafuJar}</param>
    <param>inputPath=${inputPath}</param>
    <param>outputPath=${outputPath}</param>
</pig>
</action>

收到以下错误:

E0701: XML schema error, cvc-complex-type.2.4.a: Invalid content was found starting with element 'param'. One of '{"uri:oozie:workflow:0.4":argument, "uri:oozie:workflow:0.4":file, "uri:oozie:workflow:0.4":archive}' is expected.

尝试使用参数，但没有成功

 <action>
 <pig>
    <job-tracker>${jobTracker}</job-tracker>
    <name-node>${nameNode}</name-node>                      
    <script>Population.pig</script> 
    <param>-t</param>
    <param>ColumnMapKeyPrune</param>
    <param>piggybankJar=${piggybankJar}</param>
    <param>datafuJar=${datafuJar}</param>
    <param>inputPath=${inputPath}</param>
    <param>outputPath=${outputPath}</param>
</pig>
</action>

对于 pig oozie 操作只允许参数、存档、文件和参数标签。如何传递这个 optimizer_off 选项？

Answer 1

在你的 pig 脚本中设置下面提到的属性并尝试一次。

set pig.optimizer.rules.disabled 'ColumnMapKeyPrune';
