Sanjay Radia commented on HDFS-2246: ------------------------------------ @milind ... we might [incorrectly] qualify a read for short circuit, on a multi container system .. In a multi-container environment such as linux containers or solaris zones, you are likely to give different IP addresses to each of the containers. Hence the problem you describe will not occur. Further, you would run HBase and DN within the same container or give each the same IP. I don't think linux container allow the sharing of IPs across containers. > Shortcut a local client reads to a Datanodes files directly > ----------------------------------------------------------- > > Key: HDFS-2246 > URL: https://issues.apache.org/jira/browse/HDFS-2246 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Sanjay Radia > Attachments: 0001-HDFS-347.-Local-reads.patch, HDFS-2246.20s.1.patch, > HDFS-2246.20s.2.txt, HDFS-2246.20s.3.txt, HDFS-2246.20s.4.txt, > HDFS-2246.20s.patch, localReadShortcut20-security.2patch > > -- This message is automatically generated by JIRA.
