Why Is the Error "Will not attempt to authenticate using SASL (unknown error)" Reported When Connecting to HBase?

Symptom

CloudTable HBase fails to be connected and the following error information is displayed:

Opening socket connection to server 192.168.0.107/192.168.0.107:2181. Will not attempt to authenticate using SASL (unknown error)

Possible Cause

The possible cause is as follows:

Network access failure

The HBase connection address is an internal network address, not a public network address. Consequently, direct connections to the HBase cluster from the public internet are not supported. You can ping the ZooKeeper link of HBase on a client host. If it cannot be pinged, the network connection is abnormal.

Solution

You need to apply for an ECS as the client host to install the CloudTable client. Then, you can use the client on the ECS to access the CloudTable cluster. The ECS to be applied for and the CloudTable cluster must be in the same region, VPC, subnet, and security group. In addition, you need to configure a correct DNS server address for the ECS.
