             Summary: Modify BloomFilter.write() to address memory concerns
                 Key: HADOOP-9196
                 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.
