Fail to link a sample table to its base table

[xixiz]

Given two column tables of the same name but different schemas, namely schema1.examples and schema2.examples. Then, for each of them, a corresponding sample table of the same name is created using the following commands.

create sample table schema1.examples_sample on schema1.examples options (qcs 'status’, fraction '0.1') as (select * from schema1.examples);

create sample table schema2.examples_sample on schema2.examples options (qcs 'status’, fraction '0.1') as (select * from schema2.examples);

When querying schema2.examples using "... with error;", the obtained result used schema1.examples_sample instead of schema2.examples_sample.

When deleting both sample tables then querying schema2.examples again with the same query, an error occurred as shown in the following lines.

ERROR 42X05: (SQLState=42X05 Severity=20000) (Server=snappy3/192.168.210.193[1527] Thread=ThriftProcessor-4) Table/View 'SCHEMA.EXAMPLES_SAMPLE' does not exist.
