Help for Fixing TpcdsLatticeSuggesterTest in calcite

["wangcheng (AK)" <wa...@huawei.com.INVALID>]

Hi,

I'm planning to use the lattice suggester in Calcite with TPC-DS, but the TpcdsLatticeSuggesterTest in Calcite fails in the 1st query. I run the TpcdsLatticeSuggesterTest with Disabled annotation removed.

The error is shown below:
Can't unwrap class org.apache.calcite.sql.SqlDialect from RelOptTableImpl{schema=org.apache.calcite.prepare.CalciteCatalogReader@54fcf62e, names= [tpcds, STORE_RETURNS], table=org.apache.calcite.adapter.tpcds.TpcdsSchema$TpcdsQueryableTable@531cd17a, rowType=RecordType(BIGINT SR_RETURNED_DATE_SK, BIGINT SR_RETURN_TIME_SK, BIGINT SR_ITEM_SK, BIGINT SR_CUSTOMER_SK, BIGINT SR_CDEMO_SK, BIGINT SR_HDEMO_SK, BIGINT SR_ADDR_SK, BIGINT SR_STORE_SK, BIGINT SR_REASON_SK, BIGINT SR_TICKET_NUMBER, INTEGER SR_RETURN_QUANTITY, DECIMAL(7, 2) SR_RETURN_AMT, DECIMAL(7, 2) SR_RETURN_TAX, DECIMAL(7, 2) SR_RETURN_AMT_INC_TAX, DECIMAL(7, 2) SR_FEE, DECIMAL(7, 2) SR_RETURN_SHIP_COST, DECIMAL(7, 2) SR_REFUNDED_CASH, DECIMAL(7, 2) SR_REVERSED_CHARGE, DECIMAL(7, 2) SR_STORE_CREDIT, DECIMAL(7, 2) SR_NET_LOSS)}
