the command I am using to load the sstable is

$bin/sstableloader -d nodename -u username -pw password path/to/sstable/keyspacename/tablename

this was working a few days back .I am not sure whats changed and how to debug it ? I am using datastax. I am loading the sstable from the same node which is in the cluster.ie my source and destination node are same. Has someone seen this error before ? Cassandra version : 2.1 Any Help is appreciated.

Answer 1

The exception in the stack trace comes from this piece of code:

    if (version >= Server.VERSION_3)
    {
        int size = input.getInt();
        if (size < 0)
            return null;

        return ByteBufferUtil.readBytes(input, size); // HERE !
    }

I'm wondering if you're loading sstables that have been generated by a Cassandra 2.1 or an older version .... Because the issue seems to be at the byte-encoding level.

There is also a possibility that your SSTables are corrupted.

How did you get those sstables ? From a copy of another Cassandra instance ? Generated by CQLSSTableWriter ?

I had this problem again, so debugged it a little for the root cause. The problem is if at any time you have altered your cassandra table by dropping some column. it triggers a bug for sstableLoader. That why dropping the table and creating it again works.
