nichunen updated KYLIN-3515:
----------------------------
Description: The root cause is for hive view, during cubing, kylin will
materialize the view by creating an intermediate table(drop intermediate table
first). The intermediate tables' name is like kylin_intermediate_\{view_name},
that means jobs will create tables with the same name if the same view is
referenced. So one job's intermediate table may be dropped by another job, in
such cases, error like "table not found" will happen (was: The root cause is
