Hello,
I am running a query like: select sum(amount) from
myhdfs.parquet.`claim.parquet`;
This fails with the following error at sqlline:
Query failed: Failure while running fragment. Schema is currently null. You
must call buildSchema(SelectionVectorMode) before this container can return a
schema. [00314ea1-342a-4322-ac00-f8307c554733]
Error: exception while executing query: Failure while trying to get next result
batch. (state=,code=0)
