When using the hive writeback function, several points need to be paid attention to:

1. Open the new global optimizer set global enable_nereids_planner = true
2. Close the fallback set global enable_fallback_to_original_planner=false

For some clusters upgraded from old versions, the default values ​​of the above parameters may still be old, so they need to be adjusted manually.

In addition, it is recommended to upgrade to a stable version >= 2.1.5
