Using a quick dirty stack overflow byte[] -> hextring:
> CASSANDRA 2.0 : java driver : blobs not retrieving correctly
> ------------------------------------------------------------
>
> Key: CASSANDRA-6543
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6543
> Project: Cassandra
> Issue Type: Bug
> Components: API
> Reporter: Constance Eustace

> Might be wrong place but didn't find where the bugs should go and saw some
> java-driver ones in here...
> Simple retrieval of data from a blob CQL3 column, tried getBytes() and
> getBytes() unsafe, neither seemed to matter.
> getBytes(col).array()
> Anyway, the input is 1760 bytes, and checked in cqlsh and the data looks
> correctly inserted.
> Retrieval buffer is consistently 1863 bytes... ResultSet column definitions
> indicate it is of type blob, well, and getBytes shouldn't work.
> bytebuffer.getCapacity is 1863 bytes. The first four values are definitely
> different for the retrieved BB than the one sent to storage.
> Is there a mode or something? Maybe some assumed UTF8 decode is occurring?
> Compression? The blob I'm storing has already been compressed via java's zip
> support, so a rezip would probably make it larger?
> Here is the blob value in cqlsh, I'll try to get the post-retrieval array:
