Allow applications to know that a read failed beucase block is missing
----------------------------------------------------------------------

                 Key: HDFS-532
                 URL: https://issues.apache.org/jira/browse/HDFS-532
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


I have an application that has intelligence to retrieve data from alternate 
locations if HDFS cannot provide this data. This can happen when data in HDFS 
is corrupted or the block is missing. HDFS already throws ChecksumException if 
the block is corrupted and throws a generic IOException if the block is 
missing. I would like HDFS to throw BlockMissingException when a read request 
encounters a block that has no locations associated with it.
