我在Ubuntu 14.04 32位上使用 Hadoop版本2.4.1 。 当我使用 hadoop jar user_jar.jar 命令运行示例作业时,我无法在 http://localhost:19888 (找不到页面)上看到输出< /强> 可能的原因是什么? 提前谢谢。

运行mr-jobhistory-daemon:

$ $HADOOP_HOME/sbin/mr-jobhistory-daemon.sh --config $HADOOP_CONFIG_DIR start historyserver

现在

$ jps 2135 DataNode 2339 SecondaryNameNode 2627 NodeManager 3176 JobHistoryServer 1971 NameNode 3213 Jps 2485 ResourceManager

$ netstat -ntlp | grep 19888 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 127.0.0.1:19888 0.0.0.0:* LISTEN 3176/java
