关于hadoop hive中使用hive分区功能

1. set hive.exec.dynamic.partition=true;

2. set hive.exec.dynamic.partition.mode=nonstrict;

3. set hive.exec.max.dynamic.partitions.pernode=1000;

4. insert overwrite table dividends partition(`exchange`,`symbol`) select `ymd`,`dividend`,`exchange`,`symbol` from dividends_unpartitioned;
