Jesus Camacho Rodriguez commented on HIVE-8974:
-----------------------------------------------

For {{vector_decimal_aggregate}}, statistics change. However, for {{cbo_views}} 
we get an {{java.lang.NullPointerException}}. [~julianhyde], I attach the 
stacktrace, can you help me figuring out whether this is a problem on the 
Calcite side?

> CLEAR LIBRARY CACHE
> Calcite recently (after 0.9.2, before 1.0.0) re-organized its package 
> structure and renamed a lot of classes. CALCITE-296 has the details, 
> including a description of the before:after mapping.
> This task is to upgrade to the version of Calcite that has the renamed 
> packages. There is a 1.0.0-SNAPSHOT in Apache nexus.
> Calcite functionality has not changed significantly, so it should be 
> straightforward to rename. This task should be completed ASAP, before Calcite 
> moves on.
