Subject [jira] [Resolved] (HDFS-7558) NFS gateway should throttle the data dumped on local storage
Date Tue, 19 May 2015 22:07:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.

> 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.
