Daryn Sharp commented on HDFS-11026: ------------------------------------ bq. I couldn't get a 3.0 and 2.8 datanode/namenode to talk to each other so I'm not sure if I'm doing something wrong of if this is a show stopper on the rolling upgrades (if so, I'll enter a ticket): Are you saying you can't make your patch work in a compatible way? Or you can't get stock 2.8/3.0 to work together? If the former, then this patch can't go in. If the latter, then it's a show stopper. > Convert BlockTokenIdentifier to use Protobuf > -------------------------------------------- > > Key: HDFS-11026 > URL: https://issues.apache.org/jira/browse/HDFS-11026 > Project: Hadoop HDFS > Issue Type: Task > Components: hdfs, hdfs-client > Affects Versions: 2.9.0, 3.0.0-alpha1 > Reporter: Ewan Higgs > Fix For: 3.0.0-alpha2 > > Attachments: HDFS-11026.002.patch, blocktokenidentifier-protobuf.patch > > > {{BlockTokenIdentifier}} currently uses a {{DataInput}}/{{DataOutput}} > (basically a {{byte[]}}) and manual serialization to get data into and out of > the encrypted buffer (in {{BlockKeyProto}}). Other TokenIdentifiers (e.g. > {{ContainerTokenIdentifier}}, {{AMRMTokenIdentifier}}) use Protobuf. The > {{BlockTokenIdenfitier}} should use Protobuf as well so it can be expanded > more easily and will be consistent with the rest of the system. > NB: Release of this will require a version update since 2.8.x won't be able > to decipher {{BlockKeyProto.keyBytes}} from 2.8.y. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
