yasser-chihab opened a new issue, #30040:
URL: https://github.com/apache/beam/issues/30040
### What happened?
We are trying to run a Go based **apache beam sdk 2.53** pipeline on
Dataflow, we try to use SqlTransform, but unfortunately It throws the following
error
```
Error: Unable to initialize main class org.apache.beam.fn.harness.FnHarness
Caused by: java.lang.NoClassDefFoundError:
org/apache/beam/vendor/grpc/v1p54p0/io/grpc/Channel
```
our piplie code is the following
```
package main
import (
"context"
"flag"
"fmt"
"reflect"
"strings"
"time"
"github.com/apache/beam/sdks/v2/go/pkg/beam"
"github.com/apache/beam/sdks/v2/go/pkg/beam/io/bigqueryio"
"github.com/apache/beam/sdks/v2/go/pkg/beam/log"
"github.com/apache/beam/sdks/v2/go/pkg/beam/transforms/sql"
"github.com/apache/beam/sdks/v2/go/pkg/beam/x/beamx"
)
type Workspace struct {
WorkspaceId string
}
type BqRow struct {
Date string
Line string
WordCount int64
}
func Init() {
beam.RegisterType(reflect.TypeOf((*Workspace)(nil)))
}
func main() {
ctx := context.Background()
flag.Set("runner", "dataflow")
flag.Set("project", gcpProject)
flag.Set("region", "us-east1")
flag.Set("staging_location", "gs://stream-words/binaries")
flag.Set("runner", "DirectRunner")
flag.Parse()
beam.Init()
// Create the Pipeline object and root scope.
pipeline, scope := beam.NewPipelineWithRoot()
in := beam.Create(scope,
Workspace{WorkspaceId: "ws1"},
Workspace{WorkspaceId: "ws2"},
Workspace{WorkspaceId: "ws3"},
Workspace{WorkspaceId: "ws4"},
Workspace{WorkspaceId: "ws5"},
Workspace{WorkspaceId: "ws2"},
Workspace{WorkspaceId: "ws3"},
Workspace{WorkspaceId: "ws4"},
)
fmt.Println("=======> ", in.Coder())
out := sql.Transform(scope, "SELECT COUNT(*) FROM PCOLLECTION",
sql.Input("t", in),
sql.OutputType(reflect.TypeOf(int64(0))),
sql.Dialect("calcite"),
)
writeToBQ(scope, *bigqueryDataset, out)
// Run the beam pipeline
if err := beamx.Run(ctx, pipeline); err != nil {
log.Exitf(ctx, "Failed to execute job: %v", err)
}
}
```
Do we miss anything here that can cause the issue ?
