docker - Sqoop - 导入作业失败

Question

我正在尝试通过 Sqoop 将包含 3200 万条记录的表从 SQL Server 导入 Hive。连接是 SQL Server 成功的。但是 Map/Reduce 作业没有成功执行。它给出了以下错误:

起初，作业在通过 0.0.0.0:8032 与资源管理器连接时卡住了。于是我把主机改成了127.0.0.1。然后行刑继续进行。但随后出现上述错误。即使我尝试只用 1000 行来执行这项工作，但同样的错误。此外，有时工作会被终止。

这是我的 sqoop 命令

sqoop import --connect "jdbc:sqlserver://system-ip;databaseName=TEST" --driver com.microsoft.sqlserver.jdbc.SQLServerDriver --username user1 --password password --hive-import --create-hive-table --hive-table "customer_data_1000" --table "customer_data_1000" --split-by Account_Branch_Converted -m 1 --verbose

这是我的 docker 命令以防万一:

  docker run --hostname=quickstart.cloudera --privileged=true -t -p 127.0.0.1:8888:8888 -p 127.0.

0.1:7180:7180 -p 127.0.0.1:50070:50070 -i 7c41929668d8/usr/bin/docker-quickstart

这是资源管理器日志:

我哪里错了？

Answer 1

我不能给你一个精确的解决方案，但我能做的就是告诉你根本原因是什么:

1. 尝试以非 root 用户身份运行 Sqoop 作业。
2. 检查您的 JDK 是否正确安装在主机上，您的 JAVA_HOME 是否设置正确。
3. 检查您是否已授予您正在使用的数据库的正确权限。

由于上述原因之一，您的工作失败了。由于您有足够的 v-cores 和可用内存，并且容器也正在创建中。所以，处理端一切正常，但肯定有配置错误。
