在Amazon emr hue中，sqoop导入的Oozie工作流程失败

标签： hadoop hive sqoop oozie amazon-emr

我创建了一个oozie工作流来执行从mysql到hive系统的sqoop导入。

用于创建sqoop作业的Sqoop作业成功运行，但是当我尝试执行从MySQL导入Hive的作业时，它失败了。我附上了日志

sqoop --hive-import（失败的sqoop操作）会分两步进行。

  1. 首先将一个sqoop导入到HDFS目录（我的xml中引用的targetDir）。

  2. 然后移动此sqoop导入的输出并导入Hive。

    3. 当我通过oozie运行我的sqoop作业时，我在targetDir中看到一个_SUCCESS文件，表明sqoop导入成功。只有后期（第2步）失败。

    我作为hue用户运行Oozie工作流程。

2 个答案:

答案 0 :(得分：0)

错误是因为sqoop无法找到配置单元。

尝试在运行此sqoop命令的用户的所有datanode中为hive设置env变量

编辑：

输入命令行

oozie admin -shareliblist hive

并检查tez-api-*.jar是否存在。

如果没有，则转到hdfs路径/user/oozie/share/lib/lib_DATA/hive/并检查tez-api-*.jar是否存在。如果存在，则更新sharelib oozie admin -sharelibupdate并再次检查

答案 1 :(得分：0)

Sqoop在运行时无法找到Tez jar（即＆＃34; org.apache.tez.dag.api.SessionNotRunning＆＃34;类，确切地说）。

请根据需要验证您是否有Tez罐。
