我创建了一个ooziesqoop任务来将数据从mysql导入hive。我有一个namenode和3个datanode，在namenode上还安装了hive、oozie和sqoop。
sqoop import coommand已经在namenode上测试过var cli，但是每次创建oozie sqoop任务时，它都会失败。下面是详细的错误。 2017-08-11 11:27:40,787 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 0% reduce 0% 2017-08-11 11:27:40,787 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 0% reduce 0% 2017-08-11 11:27:44,833 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 25% reduce 0% 2017-08-11 11:27:44,833 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 25% reduce 0% 2017-08-11 11:27:45,837 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 75% reduce 0% 2017-08-11 11:27:45,837 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 75% reduce 0% 2017-08-11 11:27:46,844 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 100% reduce 0% 2017-08-11 11:27:46,844 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - map 100% reduce 0% 2017-08-11 11:27:46,856 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - Job job_1502360348741_0041 completed successfully 2017-08-11 11:27:46,856 [uber-SubtaskRunner] INFO org.apache.hadoop.mapreduce.Job - Job job_1502360348741_0041 completed successfully ... 2017-08-11 11:27:46,932 [uber-SubtaskRunner] INFO org.apache.sqoop.mapreduce.ImportJobBase - Transferred 625 bytes in 12.0595 seconds (51.8263 bytes/sec) 2017-08-11 11:27:46,936 [uber-SubtaskRunner] INFO org.apache.sqoop.mapreduce.ImportJobBase - Retrieved 14 records. 2017-08-11 11:27:46,951 [uber-SubtaskRunner] INFO org.apache.sqoop.manager.SqlManager - Executing SQL statement: SELECT t.* FROM UserRole AS t WHERE 1=0 2017-08-11 11:27:46,952 [uber-SubtaskRunner] INFO org.apache.sqoop.manager.SqlManager - Executing SQL statement: SELECT t.* FROM UserRole AS t WHERE 1=0 2017-08-11 11:27:46,953 [uber-SubtaskRunner] WARN org.apache.sqoop.hive.TableDefWriter - Column updatedDate had to be cast to a less precise type in Hive 2017-08-11 11:27:46,960 [uber-SubtaskRunner] INFO org.apache.sqoop.hive.HiveImport - Loading uploaded data into Hive 2017-08-11 11:27:46,963 [uber-SubtaskRunner] ERROR org.apache.sqoop.tool.ImportTool - Encountered IOException running import job: java.io.IOException: Cannot run program "hive": error=2, 这是我的想法
Map程序作业已生成，因此应提交此脚本并在namenode上运行。是这样吗？
我对所有的env vars都很好地进行了配置，因此错误阶段（将数据导入hive表的导入工具）应该在其中一个datanode上启动。
所以我应该在集群的每个数据节点上安装配置单元吗？或者有任何配置，我可以做什么来解决这个问题？
