Subject [jira] [Created] (HDFS-5810) Unify mmap cache and short-circuit file descriptor cache
Date Wed, 22 Jan 2014 19:07:26 GMT
Colin Patrick McCabe created HDFS-5810:
------------------------------------------

             Summary: Unify mmap cache and short-circuit file descriptor cache
                 Key: HDFS-5810
                 URL: https://issues.apache.org/jira/browse/HDFS-5810
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs-client
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


We should unify the client mmap cache and the client file descriptor cache.  Since mmaps are
granted corresponding to file descriptors in the cache (currently FileInputStreamCache), they
have to be tracked together to do "smarter" things like HDFS-5182.
