  6. def dumpBuffer(conf: Configuration, data: HostMemoryBuffer, offset: Long, len: Long, prefix: String, suffix: String): String

    Debug utility to dump a host memory buffer to a file.

    Debug utility to dump a host memory buffer to a file.

    conf

    Hadoop configuration

    data

    buffer containing data to dump to a file

    offset

    starting offset in the buffer of the data

    len

    size of the data in bytes

    prefix

    prefix for a path to write the data

    suffix

    suffix for a path to write the data

    returns

    Hadoop path for where the data was written or null on error

  7. def dumpToParquet(columnarBatch: ColumnarBatch, outputStream: OutputStream): Unit

    Dump columnar batch to output stream in parquet format.

    Dump columnar batch to output stream in parquet format.

    columnarBatch

    The columnar batch to be dumped, should be GPU columnar batch. It should be closed by caller.

    outputStream

    Will be closed after writing.

  8. def dumpToParquetFile(table: Table, filePrefix: String): Option[String]

    Debug utility to dump table to parquet file.

    Debug utility to dump table to parquet file.
    It's running on GPU. Parquet column names are generated from table column type info.

    table

    the table to be dumped, should be GPU columnar batch

    filePrefix

    parquet file prefix, e.g. /tmp/my-debug-prefix-

    returns

    parquet file path if dump is successful, e.g. /tmp/my-debug-prefix-123.parquet

  9. def dumpToParquetFile(columnarBatch: ColumnarBatch, filePrefix: String): Option[String]

    Debug utility to dump columnar batch to parquet file.
