I am trying to run the following query in apache drill, I am querying data
stored in parquet files using the following query
select pan, count(*) as number_of_transactions ,
terminal_id,SUM((cast(SETTLE_AMOUNT_IMPACT as double) *-1)/100) AS
settle_amount_impact
from dfs.`/iswdata/storage/products/superswitch/parquet/transactions`
where pan like '506126%' and terminal_id like '1%' and
sink_node_name like ('SWTDB%')
and source_node_name not like ('SWTDBLsrc')
and tran_completed=1
and tran_reversed = 0
and tran_postilion_originated = 1
AND tran_type = '01'
--and pan like '506126%0011'
group by pan,terminal_id
The Schema for the data I am querying is as follows
post_tran_id LONG
post_tran_cust_id :LONG
settle_entity_id :INTEGER
batch_nr : INTEGER
prev_post_tran_id : LONG
next_post_tran_id : LONG
sink_node_name : STRING
tran_postilion_originated : DECIMAL
tran_completed : DECIMAL
tran_amount_req : DECIMAL
tran_amount_rsp : DECIMAL
settle_amount_impact : DECIMAL
tran_cash_req : DECIMAL
tran_cash_rsp : DECIMAL
tran_currency_code : STRING
tran_tran_fee_req : DECIMAL
tran_tran_fee_rsp : DECIMAL
tran_tran_fee_currency_code : STRING
tran_proc_fee_req : DECIMAL
tran_proc_fee_rsp : DECIMAL
tran_proc_fee_currency_code : STRING
settle_amount_req : DECIMAL
settle_amount_rsp : DECIMAL
settle_cash_req : DECIMAL
settle_cash_rsp : DECIMAL
settle_tran_fee_req : DECIMAL
settle_tran_fee_rsp : DECIMAL
settle_proc_fee_req : DECIMAL
settle_proc_fee_rsp : DECIMAL
settle_currency_code : STRING
However When I run the query against the dataset, I get the following exception
SYSTEM ERROR: ClassCastException:
org.apache.drill.exec.vector.NullableDecimal28SparseVector cannot be cast to
org.apache.drill.exec.vector.VariableWidthVector
More so, the same error occurs when I include a decimal field in the select
clause. Please, is there something I am missing or doing wrong, Any pointer
will be deeply appreciated
Kind Regards
Peter
