             Summary: Segment fault when using NextBatch of parquet::arrow::ColumnReader in parquet-cpp
                 Key: PARQUET-1169
                 URL: https://issues.apache.org/jira/browse/PARQUET-1169
             Project: Parquet
          Issue Type: Bug
          Components: parquet-cpp
            Reporter: Fang Jian


When I running the below code, I consistently get segment fault, not sure whether this is a bug or I did something wrong. Anyone here could help me take a look?

{code:c++}
#include <iostream>
#include <string>

#include "arrow/array.h"
#include "arrow/io/file.h"
#include "parquet/arrow/reader.h"

using arrow::Array;
using arrow::default_memory_pool;
using arrow::io::FileMode;
using arrow::io::MemoryMappedFile;
using parquet::arrow::ColumnReader;
using parquet::arrow::FileReader;
using parquet::arrow::OpenFile;

int main(int argc, char** argv) {
  if (argc > 1) {
    std::string file_name = argv[1];
    std::shared_ptr<MemoryMappedFile> file;
    MemoryMappedFile::Open(file_name, FileMode::READ, &file);
    std::unique_ptr<FileReader> file_reader;
    OpenFile(file, default_memory_pool(), &file_reader);
    std::unique_ptr<ColumnReader> column_reader;
    file_reader->GetColumn(0, &column_reader);

    std::shared_ptr<Array> array1;
    column_reader->NextBatch(1, &array1);
    std::cout << "length " << array1->length() << std::endl;

    std::shared_ptr<Array> array2;
    // raise segment fault
    column_reader->NextBatch(1, &array2);
    std::cout << "length " << array2->length() << std::endl;
  }
  return 0;
}
{code}
