Subject [jira] [Commented] (HDFS-9796) Add throttler for datanode bandwidth
Date Mon, 15 Feb 2016 19:42:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15147737#comment-15147737

Inigo Goiri commented on HDFS-9796:
-----------------------------------

As [~wheat9] points out, It looks like this approach was already considered in HDFS-7265 and
didn't go through.
In our case, we have other services running in the servers (e.g., Impala) and we want to give
higher priority to them.
For this reason, we'd like to reserve part of the bandwidth for them by throttling the DNs.

We will try if HDFS-7270 solves our issue. If so, we will mark this as duplicate to HDFS-7265.
