[ https://issues.apache.org/jira/browse/ZOOKEEPER-136?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Benjamin Reed updated ZOOKEEPER-136: Attachment: ZOOKEEPER-136.patch This patch includes the tests that Pat wrote and the fix for the problem. The fix involves three things: 1) The leader creates a FollowerSyncRequest that contains a reference to the FollowerHandler doing the sync. This allows us to get rid of the handler hashmap. 2) The pendingSyncs uses a List to track multiple syncs per change 3) CommitRequest processor was changed to take a boolean to flag whether to wait for syncs to come from the leader. sync causes hang in all followers of quorum --- Key: ZOOKEEPER-136 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-136 Project: Zookeeper Issue Type: Bug Affects Versions: 3.0.0 Reporter: Patrick Hunt Assignee: Benjamin Reed Fix For: 3.0.0 Attachments: ZOOKEEPER-136.patch The attached test causes all of the followers of a quorum to hang.

However the clients attached to the followers stall out (eventually TIMEOUT) waiting for the 1) operation to return. sync causes hang in all followers of quorum --- Key: ZOOKEEPER-136 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-136 Project: Zookeeper Issue Type: Bug Affects Versions: 3.0.0 Reporter: Patrick Hunt Assignee: Patrick Hunt Fix For: 3.0.0 Attachments: testfails_ZOOKEEPER-136.patch The attached test causes all of the followers of a quorum to hang.
