I am newbie to the Cassandra world. I am currently using Cassandra 2.0.0 with thrift 0.8.0 for storing netflow packets using libQtCassandra library. ... Is this a known issue because it did not occur when we were using Cassandra-1.2.6 and previous versions with pycassa library for accessing the database. ... How can I avoid this exception and also is there any way in which I can get back my node to running state even if it means reinstalling cassandra??? Thank You in advance for any help.
