Cause Analysis

After the service configuration is modified and the service is restarted, some directory structures of the service, such as the etc directory, are deleted and recreated. If the directory is etc or its subdirectory before the service is restarted, some system variables or parameters cannot be found when impala-shell is executed in the original directory because the directory is recreated after the service is restarted. As a result, impala-shell fails to be connected.

Procedure

Switch to any existing directory and reconnect to impala-shell.
