Hi there,
Trying to run a very simple app saving content of a dataframe to Delta Lake.
Code works great on 2.4.4 but fails on 3.0.0 preview & preview 2. Tried on both
Delta Lake 0.5.0 and 0.4.0.
Code (I know, it’s amazing):
df.write().format("delta")
.mode("overwrite")
.save("/tmp/delta_grand_debat_events");
Exception raised:
Exception in thread "main" com.google.common.util.concurrent.ExecutionError:

Any clue of something I am doing wrong?
