----------------------------------------
Hava somebody started the work locally or somebody had an objection about this
issue. I am a newbie in zookeeper and want to fix this issue at a start.
> Zookeeper should not warn about "An exception was thrown while closing send
> thread"

> Key: ZOOKEEPER-4376
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4376
> Project: ZooKeeper
> Issue Type: Bug
> Components: java client
> Affects Versions: 3.6.2
> Reporter: Gaspard Petit
> Priority: Minor
>
> In commit
> [https://github.com/apache/zookeeper/commit/11c07921c15e2fb7692375327b53f26a583b77ca]
> the message printed when closing a connection to Zookeeper was changed from
> being logged as a debug message to a warning message. The comment next to
> the message confirms that this is "expected" and therefore, it seems
> unjustified to use a warning level.
> Can we tune this down back to debug (or info) level? I would not mind
> submitting a pull request if there is consensus.
> The full error we are seeing is the following:
>
> {{An exception was thrown while closing send thread for session
> 0x1067b8748f00775.}}
>
> with stack strace:
> {{EndOfStreamException: Unable to read additional data from server sessionid
> 0x1067b8748f00775, likely server has closed socket at
> org.apache.zookeeper.ClientCnxnSocketNIO.doIO(ClientCnxnSocketNIO.java:77) at
> org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:350)
> at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1280)}}
