--------------------------------------
Summary: Kudu queries hit error "Unable to deserialize scan token"
Key: IMPALA-10058
URL: https://issues.apache.org/jira/browse/IMPALA-10058
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 4.0
Reporter: Joe McDonnell
I have seen a few test runs fail with a large number of Kudu tests failing with:
{noformat}
ImpalaBeeswaxException: ImpalaBeeswaxException: Query aborted:Unable to
deserialize scan token for node with id '0' for Kudu table
'impala::functional_kudu.alltypestiny': Not found: the table does not exist:
table_name: ""{noformat}
In the Impalad log, the errors looks like this:
{noformat}

This error would be coming from the Kudu client in this code in KuduScanner:
{noformat}
kudu::client::KuduScanner* scanner;
KUDU_RETURN_IF_ERROR(kudu::client::KuduScanToken::DeserializeIntoScanner(
scan_node_->kudu_client(), scan_token, &scanner),
BuildErrorString("Unable to deserialize scan token"));{noformat}
This has happened multiple times in the docker-based tests, but I have also
seen a couple jobs with the normal test runs.
