Description

Hi,

We have a keyspace starting with an upper-case character: Visitors.
We are trying to run a map reduce job on one of the column family of this keyspace.

To specify the keyspace it seems we have to use:
org.apache.cassandra.hadoop.
ConfigHelper.setInputColumnFamily(conf, keyspace, columnFamily);

If we do:
ConfigHelper.setInputColumnFamily(conf, "Visitors", columnFamily); we get:

com.datastax.driver.core.exceptions.InvalidQueryException: Keyspace 'visitors' does not exist
at com.datastax.driver.core.exceptions.InvalidQueryException.copy(InvalidQueryException.java:35)
at com.datastax.driver.core.DefaultResultSetFuture.extractCauseFromExecutionException(DefaultResultSetFuture.java:256)
at com.datastax.driver.core.SessionManager.setKeyspace(SessionManager.java:335)

...

And if we do:
ConfigHelper.setInputColumnFamily(conf, "\"Visitors\"", columnFamily); we get:
Exception in thread "main" java.lang.RuntimeException: InvalidRequestException(why:No such keyspace: "Visitors")
at org.apache.cassandra.hadoop.AbstractColumnFamilyInputFormat.getRangeMap(AbstractColumnFamilyInputFormat.java:339)
at org.apache.cassandra.hadoop.AbstractColumnFamilyInputFormat.getSplits(AbstractColumnFamilyInputFormat.java:125)
at org.apache.hadoop.mapred.JobClient.writeNewSplits(JobClient.java:962)
at org.apache.hadoop.mapred.JobClient.writeSplits(JobClient.java:979)
...

This is working just fine if the keyspace is lowercase.
And it was working just fine with Cassandra 2.0.6. But with Cassandra 2.0.7, and the addition of Datastax's java driver in the dependencies, I am getting this error.
