Anoop Sam John updated HBASE-15218:
-----------------------------------
Description:
The KeyValueCodec's Decoder makes NoTagsKeyValue. The WalCellCodec also makes
this Decoder and so while reading Cells after RS crash, we will loose all tags
in Cells. (While writing to WAL using WALCellCodec, we are preserving Cell
tags.)
In case of SecureWALCellCodec, we are not even writing Cell tags to WAL.
