InvalidTypeException: Invalid type for value..

[13o6]

I'm currently trying to run a workload on cassandra-2.1 after I've clone and built the latest ycsb repository. When I try to run the following command:

./bin/ycsb load cassandra-cql -p hosts="10.240.73.108" -P workloads/workloada

I get the following exception:

com.datastax.driver.core.exceptions.InvalidTypeException: Invalid type for value 1 of CQL type varchar, expecting class java.lang.String but class java.nio.HeapByteBuffer provided
    at com.datastax.driver.core.BoundStatement.bind(BoundStatement.java:190)

    at com.yahoo.ycsb.ClientThread.run(Client.java:416)
    at com.yahoo.ycsb.ClientThread.run(Client.java:363)

My ycsb keyspace has the following schema:

cqlsh> DESCRIBE ycsb.usertable 

CREATE TABLE ycsb.usertable (
    y_id text PRIMARY KEY,
    field0 text,
    field1 text,
    field2 text,
    field3 text,
    field4 text,
    field5 text,
    field6 text,
    field7 text,
    field8 text,
    field9 text
) 

Any hints are appreciated

AFAIK, we still don't work with Cassandra 2.1+ (see #293, #369).

If you have the time to try to chase down what's not working, we'd be happy to help give pointers.

Thanks for your reply @busbey , I decided to remove the folder and build it again but this time I can't even build it due to the following BUILD ERROR:

Not sure whether I should open another issue just for it or it's still relevant here.

[busbey]

what folder did you remove? that looks like your working directory has been corrupted the 'datastore-specific-assembly' is a part of the code that ships in YCSB.

The Cassandra 2.1 issue should be fixed by #454 - closing. Could you re-open if you're still having trouble with the latest version from master?
