Rakesh R updated ZOOKEEPER-1388:
--------------------------------
Description:
Multi ops: Op.create(path,..), Op.delete(path, ..), Op.setData(path, ..),
Op.check(path, ...) apis are not performing the client side path validation and
the call will go to the server side and is throwing exception back to the
client.
It would be good to provide ZooKeeper client side path validation for the multi
transaction apis. Presently its getting err codes from the server, which is
also not properly conveying the cause.
For example: When specified invalid znode path in Op.create, it giving the
following exception. This will not be useful to know the actual cause.
{code}
org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode
at org.apache.zookeeper.KeeperException.create(KeeperException.java:115)
at org.apache.zookeeper.ZooKeeper.multiInternal(ZooKeeper.java:1174)
at org.apache.zookeeper.ZooKeeper.multi(ZooKeeper.java:1115)
{code}
was:
It would be good to provide ZooKeeper client side path validation for the new
multi transaction api.
Presently the Op.create(path,..), Op.delete(path, ..), Op.setData(path, ..),
Op.check(path, ...) apis are not performing the client side path validation and
the call will go to the server side and is throwing exception back to the
client.
Fix involves method signature modification of Op apis by throwing
'KeeperException' (This will affect the backward compatibility).
Priority: Minor (was: Trivial)
> Client side 'PathValidation' is missing for the multi-transaction api.
