Wei-Chiu Chuang commented on HBASE-20900: ----------------------------------------- Extend FsDelegationToken such that it gets multiple delegation tokens at once. Possible scenarios where multiple delegation tokens may be associated with a file system: 1. Viewfs-based HDFS federation 2. HDFS at-rest encryption. The patch is sizable, but the patch is straightforward -- update the code to pass around multiple delegation tokens in protobuf messages. No test yet -- will add unit tests later. > Improve FsDelegationToken to support KMS delegation tokens > ---------------------------------------------------------- > > Key: HBASE-20900 > URL: https://issues.apache.org/jira/browse/HBASE-20900 > Project: HBase > Issue Type: Sub-task > Reporter: Wei-Chiu Chuang > Assignee: Wei-Chiu Chuang > Priority: Major > Attachments: HBASE-20900.master.001.patch > > > Currently FsDelegationToken acquires HDFS delegation token. Any tools that > use it to access encryption zone files could fail because they don't have KMS > delegation token. We should fix it. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
