[jira] [Created] (IGNITE-8421) ZkDistributedCollectDataFuture fails
to delete future data in case of concurrent deletion

---------------------------------------
Summary: ZkDistributedCollectDataFuture fails to delete future data in case of concurrent deletion
Key: IGNITE-8421
URL: https://issues.apache.org/jira/browse/IGNITE-8421
Project: Ignite
Issue Type: Bug
Components: zookeeper
Affects Versions: 2.5
Reporter: Sergey Chugunov
Assignee: Sergey Chugunov
Fix For: 2.5
In *ZkDistributedCollectDataFuture#deleteFutureData* method KeeperException.NoNodeException may be thrown but the exception isn't critical in this context and doesn't require special handling (just logging is enough).
However *deleteFutureData* relies on *ZookeeperClient#getChildren* which reacts on any exception (including NoNodeException) by killing current Ignite node.
Another implementation of *ZookeeperClient#getChildren* is needed which tolerates NoNodeException.
