Description

COPY TESTCASE FROM/TO statements are added in IMPALA-5872. They are useful in collecting metadata in a remote cluster and replicating them in another debug cluster. However, they are not supported in LocalCatalog mode yet.

copy testcase to "/tmp" select count(*) from functional.alltypes;

ERROR: ClassCastException: org.apache.impala.catalog.local.LocalFsTable cannot be cast to org.apache.impala.catalog.Table
