Ben Frank commented on CASSANDRA-4593:
--------------------------------------
I'll add it as a gotcha to that page, thanks for pointing it out.
Jonathan, you really think this isn't worth being defensive about in the
RecordReader? Seems like it presents an unclear api which is also hard to
document; since there isn't really a natural point to put it in javadoc or
anything. Doesn't seem like there is really any detriment to doing this or
something like it. looking at the code history it appears as if this has been
toyed with but not fully implemented.
> Reading the ByteBuffer key from a map job causes an infinite fetch loop

> Key: CASSANDRA-4593
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4593
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Affects Versions: 1.1.2
> Reporter: Ben Frank
> Attachments: cassandra-1.1-4593.txt
>
>
> Reading the ByteBuffer key from a map job empties the buffer. One of these
> key buffers is later used in ColumnFamilyRecordReader to figure out the last
> token that was received, then using that as a start point to fetch more rows.
> With a now empty buffer, the token defaults to the start of the range and
> thus the end of the data is never reached.
