describe_schema_versions() returns a Map<String, List<String>> with one entry. The key is an UUID and List<String> has one element, which is IP of my machine.
I think this has something to do with 'truncate' command in CLI, I can reproduce by: 1. create a CF with column1 as a secondary index 2. add some rows 3. truncate the CF 4. add some rows and do a query where column1=someValue and column2=someValue. It does not happy if the query just has column1=someValue thanks On Wed, Dec 8, 2010 at 3:17 PM, Aaron Morton <aa...@thelastpickle.com>wrote: > Jonathan suggested your cluster has multiple schemas, caused by > https://issues.apache.org/jira/browse/CASSANDRA-1824 > > Can you run this API command describe_schema_versions() , it's not listed > on the wiki yet but it will tell you how many schema versions are out there. > pycassa supports it. > > Aaron > > > On 09 Dec, 2010,at 08:19 AM, Aaron Morton <aa...@thelastpicklecom> wrote: > > Please send this to the list rather than me personally. > > Aaron > > Begin forwarded message: > > *From: *Wenjun Che <wen...@openf.in> > *Date: *08 December 2010 4:35:10 PM > *To: *aa...@thelastpickle.com > *Subject: Re: NullPointerException in Beta3 and rc1* > > I created the CF on beta3 with: > create column family RecipientChat with gc_grace=5 and comparator = > 'AsciiType' and > column_metadata=[{column_name:recipient,validation_class:BytesType,index_type:0}] > > After I added about 5000 rows, I got the error when querying the CF with > recipient='somevalue' and anotherColumn='anotherValue'. > > I tried truncating the CF and it was still getting the same error. > > The last thing I tried is upgrading to rc1 and saw the same error. > > Thanks > > > >
