----------------------------------------
Summary: BookieWatcher should not do ZK blocking operations from
ZK async callback thread
Key: BOOKKEEPER-1061
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1061
Project: Bookkeeper
Issue Type: Bug
Reporter: Matteo Merli
Assignee: Matteo Merli
Priority: Minor
Fix For: 4.5.0
In some cases, the BookieWatcher can get the ZK event thread stuck. This
happens when a ZK blocking request is issued from a ZK callback thread.
We should decouple the blocking requests in a separate executor to avoid
deadlocking ZK client.
