C: prefix based shard created improperly

Bug Resolved Done Jakub Morvay Peter Gubka Thu, 27 Apr 2017 18:39:23 +0000 Tue, 25 Jul 2023 08:24:32 +0000 Fri, 5 May 2017 00:11:44 +0000 clustering 0 4 <p>Does this need to block the release? Are prefix shards even being used in yet in Carbon?</p> <p>Tomas - can you look into this?</p> <p>I think the root cause lies here<br/> <a href="https://github.com/opendaylight/controller/blob/be338c9e1dab83e2a5ff21819b92b934ef32faee/opendaylight/md-sal/sal-distributed-datastore/src/main/java/org/opendaylight/controller/cluster/datastore/shardmanager/ShardManager.java#L562" class="external-link" target="_blank" rel="nofollow noopener">https://github.com/opendaylight/controller/blob/be338c9e1dab83e2a5ff21819b92b934ef32faee/opendaylight/md-sal/sal-distributed-datastore/src/main/java/org/opendaylight/controller/cluster/datastore/shardmanager/ShardManager.java#L562</a></p> <p>Peers are ignored during creation of prefix based shard, so this new shard automatically becomes leader.</p> <p>I tried to play with this a little bit and change this to not to ignore peers. Locally, I can see the prefix based shards are created correctly, there is only one leader and all peers are taking part in election.</p> <p>However, now there is some problem with starting DistributedShardedDOMDataTree, default shards in particular.</p> <p>I cannot really tell, if this should block the release, but without this, we cannot use prefix based shards in carbon cluster.</p> <p>Downgrading to major to keep the blocker police off my back. Prefix shard functionality was just recently added so AFAIK no app is using it at this point and thus doesn't need to block the release.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/56498/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/56498/</a></p> Development External issue ID 8328 External issue URL Rank 0|i02rv3:
