Jonathan Ellis updated CASSANDRA-1993:
--------------------------------------
Attachment: 1993-v2.txt
Thanks for the report!
v2 should provide a similar fix while avoiding an unnecessary intermediate copy.
> Word count example doesn't output the words correctly to cassandra. It
> outputs spurious data past the length of the byte array.

> Key: CASSANDRA-1993
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1993
> Project: Cassandra
> Issue Type: Bug
> Components: Contrib
> Affects Versions: 0.7.0
> Environment: All
> Reporter: Jesse Shieh
> Priority: Minor
> Fix For: 0.7.1
>
> Attachments: 1993-v2.txt, trunk-1993.txt
>
> Original Estimate: 0.08h
> Remaining Estimate: 0.08h
>
> To reproduce:
> # start a local cassandra server e.g. sudo bin/cassandra -f
> cd contrib/word_count
> ant
> bin/word_count_setup
> bin/word_count
> # check the data in cassandra, all looks fine because the words are all of
> the same length.
> # change the data in cassandra to real words, rerun the mapreduce and you'll
> see some words have spurious characters written past their length
> # this is because the word bytes are not terminated at their length
