> It seems cannot store as six multi-byte word as mysql , for chinese in utf8 ,
> it stored only 2 word for 3byte each in utf8 .
> And in hive other format , for example , text format , parquet work well in

> My hive version is 2.3.6/2.2.0 for hadoop 2.7.0 ,orc cannot work well .
> It seems that orc project fix some in version 1.6.2 and I just change the
> orc-core-1.6.2.jar in the hive lib.
> It does not work well either .
