Thanks [~yzhangal]. The patch looks good in general.
It needs to be rebased after HDFS-7573 was committed.
{quote}The patch reload the nfs.map file if the last modification time of this
file is newer than last upload.{quote}
This can be a problem especially when the system time is modified.
{quote}
// Use Time.now() to be consistent with File#lastModified()
lastUpdateTimeStaticMap = Time.now();
{quote}
Why not get the file modification time directly? Next time we can just compare
if it has been changed, and reload the file if the new timestamp is
different(newer or older).

NFS gateway dynamically reload UID/GID mapping file /etc/nfs.map
Key: HDFS-7564
URL: https://issues.apache.org/jira/browse/HDFS-7564
Project: Hadoop HDFS
Issue Type: Improvement
Components: nfs
Affects Versions: 2.6.0
Environment: HDP 2.2
Reporter: Hari Sekhon
Assignee: Yongjun Zhang
Priority: Minor
Attachments: HDFS-7564.001.patch
Add dynamic reload of the NFS gateway UID/GID mappings file /etc/nfs.map
(default for static.id.mapping.file).
It seems that the mappings file is currently only read upon restart of the
NFS gateway which would cause any active clients NFS mount points to hang or
fail.

Hari Sekhon

Would you please provide some more details about how the hang/fail relates to the loading of the map file? What's the symptom? is there any specific entry in the map file that's causing trouble? and some logs to would indicate that if there is any? Thanks.

At the moment haivng to restart the NFS gateway to pick up changes would result in the NFS mount points on clients hanging.
