Arpit Agarwal resolved HDFS-7558.
---------------------------------
Resolution: Won't Fix
Resolving as "Won't Fix." [~brandonli] figured out a workaround for this issue
i.e. mount the NFS share with the 'sync' option. This prevents the NFS client
from sending out of order data.
Brandon also updated the 2.7.0 docs with this recommendation.
We can revisit throttling if necessary.
> NFS gateway should throttle the data dumped on local storage

> Key: HDFS-7558
> URL: https://issues.apache.org/jira/browse/HDFS-7558
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: nfs
> Affects Versions: 2.7.0
> Reporter: Brandon Li
> Assignee: Arpit Agarwal
>
> During file uploading, NFS gateway could dump the reordered write on local
> storage when the accumulated data size exceeds a limit.
> Currently there is no data throttle for the data dumping, which could easily
> saturate the local disk especially when the client is on the same host as the
> gateway.
