我想設置一個oozie和sqoop工作流(我想將mySql數據備份到我的hdfs中)。 但是當我嘗試啓動我的工作時,我陷入了困境。Oozie和sqoop配置問題
我正在使用hadoop2(工作hdfs節點),oozie的最後一個版本。 我在計算機上安裝了oozie服務器(我想在部署它之前對其進行測試),在oozie conf上使用hdfs配置(core-site.xml,hdfs-site.xml,yarn-site.xml,mapred-site.xml)/haddop-conf dir)和我的hdfs在服務器上。
我已經做了基本工作流程(測試目的,我只是想看看是否sqoop工作)這樣的:
<workflow-app name="Sqoop" xmlns="uri:oozie:workflow:0.4">
<start to="Sqoop"/>
<action name="Sqoop">
<sqoop xmlns="uri:oozie:sqoop-action:0.2">
<job-tracker>yarn.resourcemanager.address:8040</job-tracker>
<name-node>hdfs://hdfs-server:54310</name-node>
<command>job --list</command>
</sqoop>
<ok to="end"/>
<error to="kill"/>
</action>
<kill name="kill">
<message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
</workflow-app>
我把這個工作流進我的HDFS。 我已經做了Java代碼開始我的工作:
OozieClient wc = new OozieClient("http://localhost:11000/oozie");
Properties conf = wc.createConfiguration();
conf.setProperty(OozieClient.APP_PATH, "hdfs://hdfs_server:54310/hive/testSqoop/sqoop-workflow.xml");
conf.setProperty("queueName", "default");
try {
String jobId = wc.run(conf);
System.out.println("Workflow job submitted");
while (wc.getJobInfo(jobId).getStatus() == WorkflowJob.Status.RUNNING) {
System.out.println("Workflow job running ...");
System.out.println("..." + wc.getJobInfo(jobId).getStatus().toString());
Thread.sleep(10 * 1000);
}
System.out.println("Workflow job completed ...");
System.out.println(wc.getJobInfo(jobId));
} catch (Exception r) {
r.printStackTrace();
}
在Oozie的webinterface我可以看到我的工作運行

當我檢查紗webinterface,我可以看到我的工作,但與狀態失敗

我真的不知道什麼是錯的。 我需要你的建議。
謝謝〜
