Chia-Ping Tsai commented on HBASE-18201:
----------------------------------------
{quote}Could we replace the way checking *_useTag_* with this code ?
{quote}
Pardon me. I don't catch the point. The useTag you mentioned is in
DataBlockEncodingTool#checkStatistics?
> add UT and docs for DataBlockEncodingTool

> There is no example, documents, or tests for DataBlockEncodingTool. We should
> have it friendly if any use case exists. Otherwise, we should just get rid of
> it because DataBlockEncodingTool presumes that the implementation of cell
> returned from DataBlockEncoder is KeyValue. The presume may obstruct the
> cleanup of KeyValue references in the code base of read/write path.
