回复： Using snappy compresscodec in hive

[Zhefu Peng <46...@qq.com>]

Hi Gopal,


Thanks for your reply! One more question, does the effect of using pure-java version is the same as that of using SnappyCodec? Or, in other words, is there any difference between these two methods, about the compression result and effect?


Looking forward to your reply and help.


Best,
Zhefu Peng

That doesn't use the Hadoop SnappyCodec, but uses a pure-java version (which is slower, but always works).

The Hadoop snappyCodec needs libsnappy installed on all hosts.
