Hello Everyone,
I have a set of parquet files which where created as a result of a batch ETL job (using Sqoop 1). I can query the fields normally without any kind of formatting and all is well... However, when i try to create a view with the following code CREATE VIEW `dfs.asra`.`vw_tbl_settlement` AS 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` I end up with the following exception org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming schema. Errors: Error in expression at index -1. Error: Missing function implementation: [castTINYINT(VARCHAR-OPTIONAL)]. Full expression: --UNKNOWN EXPRESSION--.. Fragment 0:0 [Error Id: 55c13096-085a-4d0c-9eca-5c7bbc2d1b8f on bdnode3.interswitch.com:31010]? Please What am I doing wrong Kind Regards
