hbase-client compatibility issues

Hello Team,


We are working on a cluster and upgrading the hbase version from 1.2.0 to 2.4.9. 
The client's hbase-client version is still 1.2.0. There was an issue accessing 2.4.9. After region migration, the client will not recognize the new region information and the following error will occur
 
org.apache.hadoop.hbase.NotServingRegionException: org.apache.hadoop.hbase.NotServingRegionException: hbase:meta,,1 is not online on dx-hbaseservice00.dx,16020,1


May I ask how to solve this problem without upgrading the client version? If you need to upgrade the version, are there any other compatibility issues?




thanks
Miao Wang

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
 Miao Wang

HBase 1.x and 2.x are major versions, meaning their entire APIs are incompatible, including client-to-server. Refer to this section for more
