Summary: Improve handling of lock conflicts in zk session lock
Key: DL-86
URL: https://issues.apache.org/jira/browse/DL-86
Project: DistributedLog
Issue Type: Improvement
Components: distributedlog-core
Reporter: Sijie Guo
Assignee: Sijie Guo
Fix For: 0.4.0
- lock reacquire could happen in foreground and background thread. so use a
semaphore to make sure there is only on e outstanding acquire operation.
and check if already hold lock before reacquire.
- fix handling zk sibling znode logic. as the znode is sequential znode,
the name would be different each time. so only comparing the client id and
session id of the znodes
