@RainFung would you mind sharing the codes you run and the Koalas version?
I found the origin of the issue.
When bumping koalas to 1.8.0, one of the worker nodes was still using koalas 1.5.0, which didn't introduce restore_index
as method in InternalFrame
(https://github.com/databricks/koalas/blob/master/databricks/koalas/internal.py) until version 1.8.0.
Making sure that every node uses the same version should fix it.
