我正在加入3个HIVE大表（十亿行表）。收集了所有统计数据，但性能仍然很差（查询时间为40分钟）。
我是否可以在HIVE提示中设置任何参数以获得更好的性能？
当我尝试执行时，我会看到像
这样的信息Sep 4, 2015 7:40:23 AM INFO: parquet.hadoop.ParquetInputFormat: Total input paths to process : 1
Sep 4, 2015 7:40:23 AM INFO: parquet.hadoop.ParquetFileReader: reading another 1 footers
所有表都是在BigSql中创建的，存储参数为＆＃34;存储为PARQUETFILE＆＃34;
如何在运行HIVE查询时抑制作业进度详细信息？

Koushik - This我一个月前问过的问题会让你对ORC与Parquet的表现有很好的了解。
让我问这个问题！您的数据结构是什么？这是嵌套还是奉承？如果这是一个更平坦的数据，例如可以从RDBMS中获取数据，ORC更好，因为它与数据一起存储了轻型索引，并使数据检索更快。
希望这有帮助
