> in the doc, it says lzo compression is not used by default, but actually, if cluster is configured with lzo, kylin will use it, so i review the source code, and find that kylin determine to use lzo in hbase table by compression test result, not user's configuration;
> also, we prefer snappy as default compression, will kylin support it ?
