INSERT OVERWRITE DIRECTORY '/test/hdfs_dir' ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' STORED AS ORC SELECT * FROM hive_table;

HDFS导出到本地：shell执行

hdfs dfs -get /test/hdfs_dis/file_name /linux_dir/xxx

本地文件上传到HDFS：shell执行
 

hdfs dfs -put /linux_dir/xxx/file_name /hdfs/path

HDFS文件导入到Hive表：hive执行
 

LOAD DATA INPATH '/hdfs/path/file_name' INTO TABLE table_name;

设置分区最大数量：

SET hive.exec.max.dynamic.partitions.pernode=200;
SET hive.exec.max.dynamic.partitions = 200;
