--------------------------------------

             Summary: Inserting the same row in parallel causes bad data to be returned to the client
                 Key: CASSANDRA-7695
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7695
             Project: Cassandra
          Issue Type: Bug
         Environment: Linux 3.12.21, JVM 1.7u60
Cassandra server 2.1.0 RC 5
Cassandra datastax client version 2.1.0RC1

            Reporter: Johan Bjork
            Priority: Critical
         Attachments: PutFailureRepro.java, bad-data-tid43-get, bad-data-tid43-put

Running the attached test program against a cassandra 2.1 server results in scrambled data returned by the SELECT statement. Running it against latest stable works fine.

Attached:
* Program that reproduces the failure
* Example output files from mentioned test-program with the scrambled output.

Failure mode:
The value returned by 'get' is scrambled, the size is correct but some bytes have shifted locations in the returned buffer.

Cluster info:
For the test we set up a single cassandra node using the stock configuration file.
