Subject Strange exception when storing heavy data in cassandra 2.0.0...
Date Sat, 02 Nov 2013 05:29:40 GMT
         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. Currently, I am generating about 1000 netflows/sec
and store\ing them into the database. The program is crashing with the an
exception on the lines of--- "what() :frame size reads negative value". I
re ran the program a few times with same exception after running for a few
seconds. But, after few times a new default TException occured and
Cassandra is now failing to even to startup. When I try kill and start it
up again, the exception says--" exception encountered during startup:
unfinished compactions reference missing sstables.This should never happen
since compactions are marked finished before we start removing the old
                                     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. I am just running a single
cassandra node with default settings. 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.
