Subject [jira] Updated: (CASSANDRA-1842) ColumnFamilyOutputFormat only writes the first column
Date Sun, 12 Dec 2010 02:37:01 GMT

Jonathan Ellis updated CASSANDRA-1842:
--------------------------------------

    Attachment: 1842.txt

This is a bug where the WordCount example incorrectly wraps a byte array that is subsequently
re-used w/o copying.  Fix attached.

> In CASSANDRA-1774 we fixed a problem where only the last column was being written.  However,
it appears that we only write the first one now.  This is easy to observe in the word count
example:
> {noformat}
> RowKey: text2
> => (column=word1, value=1, timestamp=1291666461685000)
> {noformat}
> is what the output for text2 looks like, but there should be another column, word2. 
If the word count is run without CFOF it works correctly.
