It seems your Kylin metadata is somewhat corrupted. In the metadata there exists a snapshot
of table PRODUCT_DIM, however its related physical file does not exist on HDFS.

You can manually fix the metadata, or if data rebuild is easy, delete all metadata and start
over again.

Is it a build error? or query error? You mentioned two scenarios, but one exception.

Hi all:

       When I build cube to run step 4: Build Dimension Dictionary, the following error occurred,how
to solve it?

When I use the dimensions of this table, this error will appear.
