Hello all,
After I test the feature of more robust approach for hive schema change
in version 1.6. I have some tests as follow:
1. Load a fact table and a lookup table correctly ,and build a model and
cube depend on these two tables correctly, but it can’t be loaded/unload this
two tables again even though I do nothing change to their schema,just load or
unload.
2. Load a fact table and a lookup table correctly ,and build a model and
cube depend on these two tables correctly, but it can’t be loaded/unload this
two tables again after I rename a fact table column.
under these two circumstances, there will print the same log in kylin.log as
follow, Is this also a bug or what the exact meaning of more robust approach
for hive schema change ?
