hadoop中从上传数据到分布式集群的操作意义和源代码分别是什么？

模型训练和预测之后，必须把预测数据上传到分布式集群，以便后续处理。


  local create_table_sql="
    create table if not exists $target_table_name (
        ......
    )
    partitioned by (pt int)
    row format delimited fields terminated by '\t' 
    lines terminated by '\n' 
    stored as textfile;
  "
  log_info $create_table_sql
  $hive -e "$create_table_sql"

  local upload_sql="load data local inpath '$data_home/$bizdate/$predict_file' into table $target_table_name partition(pt=${bizdate});"
  log_info $upload_sql
  $hive -e "$upload_sql"
