Slow Response to HBase Connection

Symptom

In the same VPC, response is slow when an external cluster connects to HBase through Phoenix.

Possible Cause

DNS has been configured. When a client connects to HBase, DNS resolves the server first, causing slow response.

Procedure

  1. Log in to the master node as user root.
  2. Run the vi /etc/resolv.conf command to open the resolv.conf file and comment out the address of the DNS server.

    For example, #1.1.1.1.
