Subject [jira] [Commented] (HBASE-10240) Remove 0.94->0.96 migration code
Date Sun, 03 Sep 2017 06:50:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151709#comment-16151709

Chia-Ping Tsai commented on HBASE-10240:
----------------------------------------

bq. Do you mean writing out with the PB MAGIC four bytes and if not there, then we read it
as old fashion Writable?
Yep.

bq. The MetaWriter is used in one place only, doing CompoundBloomFilterWriter. Could do same
trick?
If we want to encode it as PB format, we need the same trick. Or we can just replace Writable
interface by another for remove all references to Writable.
