The Impala state_vectors_data4 table appears to have a problem (Disk I/O error: Failed to open HDFS file hdfs) from the 7th Sept. 2022 onwards.
Proof:
select count(*), FROM_unixtime(hour, 'yyyy/MM/dd') as rth_date, 'WINCHESTER-WEST' as area_of_record
FROM state_vectors_data4 where lat between 51.06152 and 51.09048
and lon between -1.366071 and -1.320889
and hour between (1662447718 - (3600*24*10)) and (1662447718 + (3600*24*2))
group by rth_date order by rth_date desc;
Result: Disk I/O error: Failed to open HDFS file hdfs://nameservice1/user/opensky/tables_v4/state_vectors/hour=1657105200/part-r-00169-858ba597-246d-4210-aa4d-91c6b44665d1.snappy.parquet
