-------------------------------------
Summary: Disable distributed log replay by default
Key: HBASE-12577
URL: https://issues.apache.org/jira/browse/HBASE-12577
Project: HBase
Issue Type: Sub-task
Reporter: Enis Soztutar
Assignee: Jeffrey Zhong
Priority: Critical
Fix For: 0.99.2
Distributed log replay is an awesome feature, but due of HBASE-11094, the
rolling upgrade story from 0.98 is hard to explain / enforce.
The fix for HBASE-11094 only went into 0.98.4, meaning rolling upgrades from
0.98.4- might lose data during the upgrade.
I feel no matter how much documentation / warning we do, we cannot prevent
users from doing rolling upgrades from 0.98.4- to 1.0. And we do not want to
inconvenience the user by requiring a two step rolling upgrade.
Thus I think we should disable dist log replay for 1.0, and re-enable it again
for 1.1 (if rolling upgrade from 0.98 is not supported).
ie. undo: HBASE-10888
