Subject [jira] [Created] (CASSANDRA-8949) CompressedSequentialWriter.resetAndTruncate can lose data
Date Wed, 11 Mar 2015 16:51:38 GMT
Joshua McKenzie created CASSANDRA-8949:
------------------------------------------

             Summary: CompressedSequentialWriter.resetAndTruncate can lose data
                 Key: CASSANDRA-8949
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8949
             Project: Cassandra
          Issue Type: Bug
            Reporter: Joshua McKenzie
            Assignee: Joshua McKenzie
            Priority: Critical
             Fix For: 2.0.13, 2.1.4


If the FileMark passed into this method fully fills the buffer, a subsequent call to write
will reBuffer and drop the data currently in the buffer. We need to mark the buffer contents
as dirty in resetAndTruncate to prevent this - see CASSANDRA-8709 notes for details.
