In Hadoop configuration, find the cluster jobtracker ip address and access 50030

Company cluster, configured Hadoop. Run the job and want to check the running status, but do not know the ip address of the jobtracker machine:

Query the ip address of the hadoop jobtrack machine and view the file conf/mapred-site.xml

<? Xmlversion = "1.0"?>
<? Xml-stylesheettype = "text/xsl" href = "configuration. xsl"?>
<Configuration>
<Property>
<Name> mapred. job. tracker </name>
<Value> node1. 49001 </value>
</Property>
<Property>
<Name> mapred. local. dir </name>
<Value>/home/hadoop/hadoop_home/var </value>
</Property>
</Configuration>

Among them, mapred. job. tracker is the host (or IP) and Port of JobTracker. HOST: port.

This alias is disgusting. I checked the/etc/hosts and the hosts, slaves, and master under/etc/hadoop/conf.

2. ping node1.

Directly display the ip address, and then ip: 50030

Press enter three times and finally come out.

Http: // xxxxxx: 50030/jobtracker. jsp
