Hi xm_zzc

As I can see from logs and the code flow, the hand-off code clears the cache
from executor code while the exception is thrown from driver code during
query.
You are getting the exception because you are using local mode whereIn
executor and driver are in the same JVM. We will check on this how can we
avoid the exception in local mode scenario. Meanwhile you can continue your
testing in cluster mode.
