HIVE_PARTITION_SCHEMA_MISMATCH

Question

I'm getting this error from AWS Athena:

HIVE_PARTITION_SCHEMA_MISMATCH: There is a mismatch between the table and partition schemas. The types are incompatible and cannot be coerced. The column 'id' in table 'db.app_events' is declared as type 'string', but partition 'xxxxx' declared column 'data.entity_price' as type 'double'.

there is no connection with those fields but it gives an error. Is it a bug or am I missing something?

Solution

Schema is kept at partition level unless you inherit schema from table. See this: https://docs.aws.amazon.com/athena/latest/ug/updates-and-partitions.html
