Question

在Hive CLI中尝试在表上创建索引时，我遇到了错误

错误：Java堆空间

该行正上方是一个URL

http://hadoop-e1e-m-01:8088/taskdetails.jsp?jobid=job_1447411380955_0006&tipid=task_1447411380955_0006_m_000000

但该网址无法访问。当我访问该URL时，我发现以下内容

HTTP ERROR 404

Problem accessing /taskdetails.jsp. Reason:

NOT_FOUND

我已通过发出mr-jobhistory-daemon.sh start historyserver

启用了作业历史记录

问题我应该启动什么守护程序或服务才能访问该页面？
