Go Build Problem with Vendor

[ljr900723 (Jierui Liu)]

I want to use the parquet-go lib (https://github.com/xitongsys/parquet-go) in my project, but I meet a problem when I build the project. The following is steps to reproduce the problems:

1. Create a new project, named temp, add write the following code into main.go

package main

import (
	"github.com/xitongsys/parquet-go/ParquetFile"
	"github.com/xitongsys/parquet-go/ParquetWriter"
)

type Model struct {
	F1 string `parquet:"name=name, type=UTF8"`
}

func main() {
	// Write
	fw, _ := ParquetFile.NewLocalFileWriter("/tmp/test.parquet")
	pw, _ := ParquetWriter.NewParquetWriter(fw, new(Model), 4)
	stu := Model{F1: "f1"}
	pw.Write(stu)
	fw.Close()
}

The code structure should be:

$GOPATH/src
|-- temp
    |-- main.go

2. Use “go get github.com/xitongsys/parquet-go/…” to download required libs. After this, the code structure should be:

$GOPATH/src
|-- cloud.google.com
|-- github.com
|-- go.opencensus.io
|-- golang.org
|-- google.golang.org
|-- gopkg.in
|-- temp
    |-- main.go

3. Use “go build” to build the project. There will be no problem.

4. Copy all dependences into “vendor”:

$GOPATH/src
|-- cloud.google.com
|-- github.com
|-- go.opencensus.io
|-- golang.org
|-- google.golang.org
|-- gopkg.in
|-- temp
    |-- main.go
    |-- vendor
        |-- cloud.google.com
        |-- github.com
        |-- go.opencensus.io
        |-- golang.org
        |-- google.golang.org
        |-- gopkg.in

Then run “go build”, but it is failed as follows:

$ go build
vendor/github.com/colinmarc/hdfs/client.go:14:2: use of internal package github.com/colinmarc/hdfs/internal/protocol/hadoop_hdfs not allowed
vendor/github.com/colinmarc/hdfs/client.go:15:2: use of internal package github.com/colinmarc/hdfs/internal/rpc not allowed

5. Then I delete all dependences under $GOPATH/src:

$GOPATH/src
|-- temp
    |-- main.go
    |-- vendor
        |-- cloud.google.com
        |-- github.com
        |-- go.opencensus.io
        |-- golang.org
        |-- google.golang.org
        |-- gopkg.in

Then run “go build”, but it is also failed with a different error:

$ go build
vendor/github.com/colinmarc/hdfs/client.go:13:2: cannot find package "github.com/colinmarc/hdfs/v2/hadoopconf" in any of:
	/Users/jrliu/Projects/go_temp/src/temp/vendor/github.com/colinmarc/hdfs/v2/hadoopconf (vendor tree)

	/Users/jrliu/Projects/go_temp/src/github.com/colinmarc/hdfs/v2/hadoopconf (from $GOPATH)

	/Users/jrliu/Projects/go_temp/src/github.com/colinmarc/hdfs/v2/internal/rpc (from $GOPATH)

Can anyone help me to figure out the problem? I will very appreciate that!
