----------------------------------

             Summary: "std::bad_cast" on mac os when reading from 
FlightStreamReader
                 Key: ARROW-15669
                 URL: https://issues.apache.org/jira/browse/ARROW-15669
             Project: Apache Arrow
          Issue Type: Bug
          Components: FlightRPC
    Affects Versions: 7.0.0, 6.0.0
            Reporter: Yifei Yang


When calling "FlightStreamReader::ReadAll()", got "std::bad_cast exception". 
This happens only on mac os, it works fine on linux (tested on ubuntu).

Code snippet:

Construction of FlightDataStream inside server's DoGet():

{{auto schema = ::arrow::schema({}}
{{{field("f0", ::arrow::int32())},}}
{{{field("f1", ::arrow::int32())},}}
{{{field("f2", ::arrow::int32())},}}
{{});}}

{{auto array_0_0 = Arrays::make<::arrow::Int32Type>(\{0, 1, 2, 3, 4, 5, 6, 7, 
8, 9}).value();}}
{{auto array_0_1 = Arrays::make<::arrow::Int32Type>(\{10, 11, 12, 13, 14, 15, 
16, 17, 18, 19}).value();}}
{{auto array_0_2 = Arrays::make<::arrow::Int32Type>(\{20, 21, 22, 23, 24, 25, 
26, 27, 28, 29}).value();}}

{{auto rb_0 = ::arrow::RecordBatch::Make(schema, 10, \{array_0_0, array_0_1, 
array_0_2});}}
{{auto rb_1 = ::arrow::RecordBatch::Make(schema, 10, \{array_0_0, array_0_1, 
array_0_2});}}

{{auto rb_reader = ::arrow::RecordBatchReader::Make(\{rb_0, rb_1});}}

{{return std::make_unique<::arrow::flight::RecordBatchStream>(*rb_reader);}}

 

Retrieve record batches from stream at client:

{{std::unique_ptr<::arrow::flight::FlightStreamReader> reader;}}

{{st = client->DoGet(ticket, &reader);    // ticked is well constructed}}

{{{}std::shared_ptr<::arrow::Table> table;{}}}{{{}st = 
reader->ReadAll(&table);{}}}

 

Thanks!
