I used jdbc: hive2 to connect Impala, but the problem was that after flashing new metadata on a table, I encountered two errors when accessing the table after a period of time
Failed to load metadata for table
Could not retrieve transaction read-only status from server
This situation occurs randomly, which is why
My hiveServer2 is highly available. Impala version 3.2
How to solve the problem where the same version of hiveServer2 is not highly available in the testing environment
