Michael Semb Wever updated CASSANDRA-21619:
-------------------------------------------
Status: Open (was: Triage Needed)
> Name the keyspace and table when deserialization meets an unknown column
> ------------------------------------------------------------------------
>
> Key: CASSANDRA-21619
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21619
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Observability/Logging
> Reporter: Michael Semb Wever
> Priority: Low
> Fix For: 7.x
>
>
> CASSANDRA-18346 added the keyspace and the table to the unknown column error
> in {{ColumnSubselection}}:
> {code}
> Unknown column id in table cycling.route during deserialization
> {code}
> Three sibling sites still report the column name alone:
> * {{Columns.Serializer.deserialize}}
> * {{SerializationHeader.Component.toHeader}}
> * {{RowFilter.Expression.Serializer.deserialize}}
> {code:java}
> throw new RuntimeException("Unknown column " +
> UTF8Type.instance.getString(name) + " during deserialization");
> {code}
> A column name such as {{id}} is rarely unique across a schema, so an operator
> who reads the message in a log cannot tell which table failed. The message
> reaches the log during schema propagation, which is when it matters most.
> The patch reports the keyspace and the table at all three sites, in the
> wording CASSANDRA-18346 established. {{SchemaTest.selectExpectingError}}
> matched the old message, so it now matches the new one.
> Patch:
> [mck/CASSANDRA-21619/trunk|https://github.com/thelastpickle/cassandra/tree/mck/CASSANDRA-21619/trunk]
> Provenance:
> [721f34c6a0|https://github.com/datastax/cassandra/commit/721f34c6a0072eed1efc05c1e460c445a01bea22]
> by Brandon Williams. That commit changes {{Columns}} alone; this patch
> extends the same change to the two remaining sites.
