Hi Gautam I have been able to narrow down the troublesome column to settlement_date.
I still see the same error when I run the select query instead. The complete stacktrace of the errors is as follows org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming schema.

SELECT id, settlement, settlement_type, to_timestamp(to_char(settlement_date, '#')) as settlement_date ,transaction_id, transaction_type, settlement_institution, settlement_institution_bank_domain_id, domain_i,product_group_id, channel_id FROM `dfs`.`***`.`/tbl_settlement` Could you narrow down on the column which is causing this error? Also, can you please set alter session set `exec.errors.verbose` = true and provide the stack trace from the console.
