[jira] [Comment Edited] (MESOS-970) Upgrade bundled leveldb to 1.18

    [ https://issues.apache.org/jira/browse/MESOS-970?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15293788#comment-15293788 ]

Great to hear!

Agents do not use leveldb, so no point in building agents with different versions of leveldb.

We need to test masters with different version of level db. For testing wire format compatibility, make sure master writes to replicated log using leveldb 1.4 and tries to recover with leveldb 1.18. And vice-versa. This is probably easiest to do with some masters using 1.4 and some masters using 1.18 in your quorum. Note that you need to start masters with replicate log registry. For testing recovery, you can just induce leader elections by restarting masters.
