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) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
