TisonKun reassigned ZOOKEEPER-3290:
-----------------------------------
Assignee: TisonKun
> Throw detailed KeeperException when a transaction failed
> --------------------------------------------------------
>
> Key: ZOOKEEPER-3290
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3290
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.5.4, 3.4.13
> Reporter: TisonKun
> Assignee: TisonKun
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.15, 3.5.6
>
> Time Spent: 3h 50m
> Remaining Estimate: 0h
>
> Assume we execute the follow statements
> {code:java}
> ZooKeeper zk = ...;
> zk.multi(Arrays.asList(
> Op.check(path1, -1),
> Op.delete(path2, -1)));
> {code}
> If path1 or path2 didn't exist, we got an exception
> {{KeeperException.NoNodeException}} without which of them doesn't exist.
> The reason is when we executed {{PrepRequestProccessor#pRequest}} in
> {{PrepRequestProccessor#L804}}, it processed
> {{KeeperException.NoNodeException}} which contained path info.
> However, we generated {{ErrorTxn}} which only contains {{err}} field
> represented error code and lost path info. Maybe a reasonable resolution is
> extend {{ErrorTxn}} to contain path info or a general {{data}} byte array.
