Arpit Agarwal commented on HADOOP-10776: ---------------------------------------- +1 on marking them public. Apart from downstream projects many applications have come to rely on these interfaces. > Open up Delegation token fetching and renewal to STORM (Possibly others) > ------------------------------------------------------------------------ > > Key: HADOOP-10776 > URL: https://issues.apache.org/jira/browse/HADOOP-10776 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Robert Joseph Evans > Priority: Blocker > > Storm would like to be able to fetch delegation tokens and forward them on to > running topologies so that they can access HDFS (STORM-346). But to do so we > need to open up access to some of APIs. > Most notably FileSystem.addDelegationTokens(), Token.renew, > Credentials.getAllTokens, and UserGroupInformation but there may be others. > At a minimum adding in storm to the list of allowed API users. But ideally > making them public. Restricting access to such important functionality to > just MR really makes secure HDFS inaccessible to anything except MR, or tools > that reuse MR input formats. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
