hadoop - 用于 sqoop 导入的 Oozie 工作流在 Amazon emr hue 中失败

Question

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

我用于创建 sqoop 作业的 Sqoop 作业成功运行，但是当我尝试执行作业以从 MySQL 导入 Hive 时，它​​失败了。这里我附上了日志

sqoop --hive-import(失败的 sqoop 操作所做的)分两步发生。

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

2. 然后将此 sqoop 导入的输出移动并导入到 Hive 中。

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)失败了。

我以 hue 用户身份运行 Oozie 工作流程。

Answer 1

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

请验证您是否有所需的 Tez jar 。
