------------------------------------------
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.
