Tsz Wo (Nicholas), SZE updated HADOOP-6566: ------------------------------------------- Hadoop Flags: [Reviewed] +1 patch looks good. > Hadoop daemons should not start up if the ownership/permissions on the > directories used at runtime are misconfigured > -------------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-6566 > URL: https://issues.apache.org/jira/browse/HADOOP-6566 > Project: Hadoop Common > Issue Type: New Feature > Components: security > Reporter: Devaraj Das > Assignee: Arun C Murthy > Fix For: 0.22.0 > > Attachments: HADOOP-6566_yhadoop20.patch, > HADOOP-6566_yhadoop20.patch, HADOOP-6566_yhadoop20.patch, > HADOOP-6566_yhadoop20.patch > > > The Hadoop daemons (like datanode, namenode) should refuse to start up if the > ownership/permissions on directories they use at runtime are misconfigured or > they are not as expected. For example, the local directory where the > filesystem image is stored should be owned by the user running the namenode > process and should be only readable by that user. We can provide this feature > in common and HDFS and MapReduce can use the same. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
