我正在使用sqoop操作的oozie工作流程,我希望从命令行获取这些sqoop操作的日志(stdout)。
这是我认为可行的:
oozie job -info 0000002-170819062150496-oozie-oozi-W
打印操作的job_id:
------------------------------------------------------------------------------------------------------------------------------------
0000002-170819062150496-oozie-oozi-W@sqoop-import-shard_1 OK job_1503124774831_0013 SUCCEEDED -
------------------------------------------------------------------------------------------------------------------------------------
0000002-170819062150496-oozie-oozi-W@sqoop-import-shard_2 OK job_1503124774831_0014 SUCCEEDED -
------------------------------------------------------------------------------------------------------------------------------------
然后我用:
mapred job -logs job_1503124774831_0013
但是这只给出了mapreduce日志。我可以从Hue
看到的Sqoop stdout日志,如处理的记录数, - last-value(在增量的情况下)不可用。
有办法获得它们吗?
编辑:添加sqoop配置和工作流文件。

在查看public void printFields(Object obj) throws Exception {
Class<?> objClass = obj.getClass();
Field[] fields = objClass.getFields();
for(Field field : fields) {
String name = field.getName();
Object value = field.get(obj);
System.out.println(name + ": " + value.toString());
}
}
之后找到了获取stdout日志的方法。
使用以下方式从oozie收到job_id之后:
mapred job help
使用以下方式获取作业的尝试列表:
oozie job -info 0000002-170819062150496-oozie-oozi-W
所以我跑了:mapred job -list-attempt-ids <job-id> <task-type> <task-state>
给了我mapred job -list-attempt-ids job_1503124774831_0022 MAP completed
现在,我能够使用以下方式获取具有sqoop数据的尝试日志:
attempt_1503124774831_0022_m_000000_0
