--------------------------------
Summary: Support squash and range in NFS static user id mapping
Key: HDFS-6498
URL: https://issues.apache.org/jira/browse/HDFS-6498
Project: Hadoop HDFS
Issue Type: Improvement
Components: nfs
Reporter: Brandon Li
HDFS-6435 adds static user group name id mapping. The mapping is a one to one
mapping.
What makes this feature easy to use is to support squash and range based
mapping as that in traditional NFS configuration (e.g.,
http://manpages.ubuntu.com/manpages/hardy/man5/exports.5.html)

# Mapping for client foobar:
# remote local
uid 0-99 - # squash these
uid 100-500 1000 # map 100-500 to 1000-1500
gid 0-49 - # squash these
gid 50-100 700 # map 50-100 to 700-750
