> Key: CASSANDRA-10481
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10481
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Environment: Linux
> Reporter: Joseph Allemandou
> Assignee: Philip Thompson
> Fix For: 2.2.x

>
> When using CqlOutputFormat with a quoted keyspace containing capital letters,
> the initialisation of the CqlRecordWriter fails.
> In the code,error is hapenning at metadata table creation in the core
> constructor:
> {code:title=CqlRecordWriter.java-main constructor|borderStyle=solid}
> CqlRecordWriter(Configuration conf) {
> ...
> try
> {
> String keyspace = ConfigHelper.getOutputKeyspace(conf);
> try (Session client =
> CqlConfigHelper.getOutputCluster(ConfigHelper.getOutputInitialAddress(conf),
> conf).connect(keyspace))
> {
> ringCache = new NativeRingCache(conf);
> if (client != null)
> {
> TableMetadata tableMetadata =
> client.getCluster().getMetadata().getKeyspace(client.getLoggedKeyspace()).getTable(ConfigHelper.getOutputColumnFamily(conf));
> ...
> }
> {code}
> It seemed to be dues to the reused function Metadata.handleId(keyspace) that,
> applied mulitple times, removes uoptes and finally lowercase the keyspace
> name.
> A valid solution (working for us at WMF) is to reuse the keyspace variable
> defined earlier instead of using the client one.
