Subject [jira] [Commented] (CASSANDRA-7093) ConfigHelper.setInputColumnFamily incompatible with upper-cased keyspaces since 2.0.7
Date Tue, 20 May 2014 23:36:38 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14004128#comment-14004128

Alex Liu commented on CASSANDRA-7093:
-------------------------------------

[~brandon.williams] I was told that Java driver doesn't need to quote the KS and Table name,
but TIL it needs quoted, I attach one more patch here. I can open another ticket if it can't
be committed to this ticket.

> 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.
