List of inputFileChanged() Examples

Examples of inputFileChanged()

org.apache.hadoop.hive.ql.exec.mr.ExecMapperContext.inputFileChanged()
For CompbineFileInputFormat, the mapper's input file will be changed on the fly, and the input file name is passed to jobConf by shims/initNextRecordReader. If the map local work has any mapping depending on the current mapper's input file, the work need to clear context and re-initialization after the input file changed. This is first introduced to process bucket map join. @return is the input file changed?

  public void process(Writable value) throws HiveException {
    // A mapper can span multiple files/partitions.
    // The serializers need to be reset if the input file changed
    ExecMapperContext context = getExecContext();
    if (context != null && context.inputFileChanged()) {
      // The child operators cleanup if input file has changed
      cleanUpInputFileChanged();
