Chia-Ping Tsai commented on HBASE-17882: ---------------------------------------- bq. Would this be a problem? No, i just noticed that KeyValueCompression is deprecated and it is used in the WalEdit only. bq. Concern is a new version being able to read old WALs It is a nice reason. Thanks for your feedback.
