50030,50060,50070,50075,50090 - Pentesting Hadoop

Information taken from the book Network Security Assesment 3rd Edition

Basic Information

Apache Hadoop is an open source framework supporting the distributed storage and processing of large datasets using computer clusters. Storage is handled by the Hadoop Distributed File System (HDFS) and processing is performed by using MapReduce and other applications (e.g., Apache Storm, Flink, and Spark) via YARN.

Figure 15-1. Hadoop 2.0 architecture

You can query MapReduce and HDFS services by using the Nmap scripts listed in the following table (including details of the default ports). At the time of writing, Metasploit does not support Hadoop.

Script name	Port	Purpose
hadoop-jobtracker-info	50030	Retrieve information from MapReduce job and task tracker services
hadoop-tasktracker-info	50060
hadoop-namenode-info	50070	Retrieve info from HDFS name node
hadoop-datanode-info	50075	Retrieve info from HDFS data node
hadoop-secondary-namenode-info	50090	Retrieve info from HDFS secondary name node

Lightweight Python and Go HDFS clients are available online. Hadoop runs without authentication by default. You can configure HDFS, YARN, and MapReduce services to use Kerberos.
