-----------------------------------
Summary: KeeperException is good to have a error message field
besides path
Key: ZOOKEEPER-3520
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3520
Project: ZooKeeper
Issue Type: Bug
Components: server
Reporter: TisonKun
We trickily set a diagnosis msg as {{path}} of {{KeeperException}} in
{{CreateMode}}(see code snippet below) because {{KeeperException}} doesn't have
a dedicated error message field. It is good to have a {{diagnosis}} field
beside {{path}} for error message beyond a path.
{code:java}
// CreateMode#L136
String errMsg = "Received an invalid flag value: " + flag + " to convert to a
CreateMode";
LOG.error(errMsg);
throw new KeeperException.BadArgumentsException(errMsg);
{code}
