David Smiley commented on SOLR-17972:
-------------------------------------
Wouldn't a connection loss make ephemeral nodes disappear, which is how the
locks are held?
> DistributedMultiLock can fail to release some locks if ZK connection loss
> occurs

> Key: SOLR-17972
> URL: https://issues.apache.org/jira/browse/SOLR-17972
> Project: Solr
> Issue Type: Bug
> Reporter: Pierre Salagnac
> Priority: Minor
>
> This bug occurs only when run the cluster with distributed cluster processing
> (no overseer).
> If a Zookeeper connection loss occurs when creating one of the locks of a
> {{DistributedMultiLock}}, any other locks of the same multi-lock that were
> already created will not be released., This will prevent the non releases
> lock to be acquired again by other operations until the session is lost,
> causing removal of the ephemeral node.
> Additionally, cluster maintenance operations will wait forever to acquire the
> required locks, and consume thread from the node pool for distributed cluster
> operations. Eventually, all thread will be used future operation will be
> rejected because the queue is full.
