             Summary: [89-fb] Better error handling for the compound bloom filter 
                 Key: HBASE-10083
                 URL: https://issues.apache.org/jira/browse/HBASE-10083
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.89-fb
            Reporter: Liyin Tang
            Assignee: Liyin Tang


When RegionServer failed to load a bloom block from HDFS due to any timeout or other reasons, it threw out the exception and disable the entire bloom filter for this HFile. This behavior does not make too much sense, especially for the compound bloom filter. 

Instead of disabling the bloom filter for the entire file, it could just return a potentially false positive result (true) and keep the bloom filter available.
