James commented on HADOOP-9196:
-------------------------------
That would definitely work. I think it violates good OO principles to an
extent (open/close principle, encapsulation), so I was hoping for a more
elegant solution, but in this case I suppose it's worth the trade-off.

> URL: https://issues.apache.org/jira/browse/HADOOP-9196
> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: James
> Priority: Minor
>
> It appears that org.apache.hadoop.util.bloom.BloomFilter's write() method
> creates a byte array large enough to fit the entire bit vector into memory
> during serialization. This is unnecessary and may cause out of memory issues
> if the bit vector is sufficiently large and memory is tight.
