hadoop kerberos setup

Last week, the team led the research to Kerberos, to be used in our large cluster, and the research task was assigned to me. This week's words were probably done with a test cluster. So far the research is still relatively rough, many online data are CDH clusters, and our cluster is not used CDH, so in the process of integrating Kerberos there are some differences. The test environment is a cluster of 5 mac

Apache Hadoop configuration Kerberos Guide Generally, the security of a Hadoop cluster is guaranteed using kerberos. After Kerberos is enabled, you must perform authentication. After verification, you can use the GRANT/REVOKE statement to control role-based access. This arti

Most Hadoop clusters adopt Kerberos as the authentication protocolInstalling the KDC Starting Kerberos authentication requires the installation of the KDC server and the necessary software. The command to install the KDC can be executed on any machine. Yum-y Install krb5-server krb5-lib krb5-auth-dialog krb5-workstation Next, install the

I recently tried to build the environment for Hadoop, but I really don't know how to build it. The next hop was a step-by-step error. Answers from many people on the Internet are also common pitfalls (for example, the most typical is the case sensitivity of commands, for example, hadoop commands are in lower case, and many people write Hadoop, so when you encount
