 Description   

We are trying to read from a SimpleDataStoreClient which points to a shard which has some data written in a previous step and the read seems to always fail with:

Caused by: org.opendaylight.controller.cluster.databroker.actors.dds.ProxyHistory$RequestReplayException: Failed to find proxy for ReadTransactionRequest

{target=member-1-datastore-Shard-id-ints!-fe-1-chn-1-txn-0-0, sequence=0, replyTo=Actor[akka://opendaylight-cluster-data/user/$o#-1387267143], path=/(tag:opendaylight.org,2017:controller:yang:lowlevel:target?revision=2017-02-15)id-ints/id-int}

Attached are DEBUG logs, although DEBUG is only turned on only for the step that tries to create the client and execute the read.

We are looking to build Carbon RC2 tomorrow 5/18 at 23:59 UTC time assuming there are no blocker bugs. Is there an ETA for when a fix can be merged and this bug resolved for stable/carbon branch?

Comment by Robert Varga [ 17/May/17 ]

Replay logs indicate that this was a quick txchain open + read + txchainclose. All of these messages have been processed, at which point we end up forwarding the request.

Let's enforce that rule: https://git.opendaylight.org/gerrit/57315
