Karthik Kambatla updated HDFS-3907: ----------------------------------- Fix Version/s: (was: 2.5.0) 2.6.0 > Allow multiple users for local block readers > -------------------------------------------- > > Key: HDFS-3907 > URL: https://issues.apache.org/jira/browse/HDFS-3907 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Affects Versions: 1.0.0, 2.0.0-alpha > Reporter: Eli Collins > Assignee: Eli Collins > Fix For: 2.6.0 > > Attachments: hdfs-3907.txt > > > The {{dfs.block.local-path-access.user}} config added in HDFS-2246 only > supports a single user, however as long as blocks are group readable by more > than one user the feature could be used by multiple users, to support this we > just need to allow both to be configured. In practice this allows us to also > support HBase where the client (RS) runs as the hbase system user and the DN > runs as hdfs system user. I think this should work secure as well since we're > not using impersonation in the HBase case. -- This message was sent by Atlassian JIRA (v6.2#6252)
