[GitHub] [pulsar] dlsprague opened a new issue #9142: ManagedLedgerException using readers
dlsprague opened a new issue #9142:
URL: https://github.com/apache/pulsar/issues/9142
If user needs to stop or some error stops the service and its not noticed for a while on restart the reader might get these errors.
This error is only recoverable when waiting for a couple of hours and then starting the reader again.
Getting the following errors every so often when restarting reader code:g
Received error from server: **Failed to get batch size for entry** org.apache.bookkeeper.mledger.ManagedLedgerException$NonRecoverableLedgerException: **No such ledger exists on Metadata Server**
Received unknown request id from server: 12
Received error from server: Failed to get batch size for entry org.apache.bookkeeper.mledger.ManagedLedgerException: Incorrect parameter input
This only occurs using a reader instead of a consumer or producer.
The only fix is to keep waiting and restarting the connection until that error doesn't come from pulsar.
Broker is running on 2.6.0 version.

User has set up reader to look for earliest message. Attached is how that is configured along with client log.

@dlsprague Did you set any retention policy on the topic? It seems that the ledgers are deleted because there was no ledger exists on the metadata server.
