Arpit Gupta commented on HDFS-2246: ----------------------------------- the javadoc for BlockReaderLocal states The client performing short circuit reads must be running as the same user as that of the datanode. Where as the impl states that 'dfs.block.local-path-access.user' needs to set on the dn to the appropriate user. We should update the javadoc with that info. > 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-branch-0.20-security-205.patch, > HDFS-2246-branch-0.20-security.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.
