Re: cassandra on re-Start
Hi, I think you did not get what i stated above: I will restate the complete problem again. I had created a keyspace named 'XYZ' in linux. I was able to access it through the java app. The system was then restarted once. Now when we tried to access the keyspace 'XYZ' ,it says it cannot locate 'XYZ'. ( I am trying to access it through a java app ,also through cqlsh and cassandra-cli) And when i try to recreate the keyspace 'XYZ' ,it gives a Ttransport exception. The keyspace 'DA' folder still exists in the hard disk. *I am not able to access it.* On Fri, Jul 6, 2012 at 4:33 AM, aaron morton aa...@thelastpickle.comwrote: Sounds like this problem in 1.1.0 https://issues.apache.org/jira/browse/CASSANDRA-4219 upgrade if you are on 1.1.0 If not please paste the entire exception.

Re: insert data in cassandra from .net..
Thnx a lot :) :) On Sat, Apr 14, 2012 at 11:59 PM, aaron morton aa...@thelastpickle.comwrote: but using insert query of cql is not working because i have fields in my table which has null values for the columns and cassandra would not take null values. You do not need to insert the null values. How they are handled depends on the .net client you are using. If you really want to insert them try using an empty string.

You should use the full type names, e.g.
create column family MyColumnFamily with comparator=UTF8Type;
2012/3/26 puneet loya puneetl...@gmail.com
It is giving errors like Unable to find abstract-type class
'org.apache.cassandra.db.marshal.utf8'
and java.lang.RuntimeException:

'catalogueId' as hex bytes
where catalogueId is a column that has utf8 as its data type. they
may be just synactical errors..
Please suggest if u can help me out on dis??
