Plamen Jeliazkov commented on HDFS-12977: ----------------------------------------- Attached new patch with whitespace changes removed and ASL added where needed. I am still investigating failing unit tests but so far they seem unrelated. I again worked with Konstantin offline for the following changes: 1) Changed StateContext interface name to AlignmentContext. 2) Renamed NNStateContext to GlobalStateIdContext. > Add stateId to RPC headers. > --------------------------- > > Key: HDFS-12977 > URL: https://issues.apache.org/jira/browse/HDFS-12977 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ipc, namenode > Reporter: Konstantin Shvachko > Assignee: Plamen Jeliazkov > Priority: Major > Attachments: HDFS_12977.trunk.001.patch, HDFS_12977.trunk.002.patch, > HDFS_12977.trunk.003.patch, HDFS_12977.trunk.004.patch, > HDFS_12977.trunk.005.patch > > > stateId is a new field in the RPC headers of NameNode proto calls. > stateId is the journal transaction Id, which represents LastSeenId for the > clients and LastWrittenId for NameNodes.
