Thank you for your answer.
As an HBase operation and maintenance personnel, I have a relatively shallow
understanding of some excuses. Looking at the above link, I need to upgrade my
HBase client. Would you also like to ask if there are any potential issues
after upgrading? The hbase environment here is dual server room, and a set of
clients needs to access the 1.2.0 and 2.4.9 clusters. Currently, we have the
aforementioned issue with accessing 1.2.0.
thanks
