It Takes a Long Time to Access HBase from a Client Outside a Security Cluster

Symptom

A user creates an MRS security cluster, installs a cluster client on a node outside the cluster, and runs the hbase shell command to access HBase. It is found that the access to HBase is very slow.

Cause Analysis

Kerberos authentication is required for a security cluster. You need to configure the hosts file on the client node to ensure that the access speed is not affected.

Procedure

Copy the content of the hosts file on the cluster node to the hosts file on the node where the client is installed.
