stack commented on HBASE-17882: ------------------------------- Agreed. Concern is a new version being able to read old WALs. I've not looked in a while. Would this be a problem? > Why do the WalEdit implement the Writable interface > --------------------------------------------------- > > Key: HBASE-17882 > URL: https://issues.apache.org/jira/browse/HBASE-17882 > Project: HBase > Issue Type: Brainstorming > Reporter: Chia-Ping Tsai > Priority: Minor > > Do we have any use cases? (serialize/deserialize the WalEdit between mapper > and reducer?) If not, we should make WalEdit not implement the Writable > interface. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
