Erik Krogen updated HDFS-14726: ------------------------------- Target Version/s: 2.10.0 > Fix JN incompatibility issue in branch-2 due to backport of HDFS-10519 > ---------------------------------------------------------------------- > > Key: HDFS-14726 > URL: https://issues.apache.org/jira/browse/HDFS-14726 > Project: Hadoop HDFS > Issue Type: Bug > Components: journal-node > Affects Versions: 2.10.0 > Reporter: Chen Liang > Assignee: Chen Liang > Priority: Blocker > Attachments: HDFS-14726-branch-2.001.patch > > > HDFS-10519 has been backported to branch-2. However HDFS-10519 introduced an > incompatibility issue between NN and JN due to the new protobuf field > {{committedTxnId}} in {{HdfsServer.proto}}. This field was introduced as a > required field so if JN and NN are not on same version, it will run into > missing field exception. Although currently we can get around by making sure > JN always gets upgraded properly before NN, we can potentially fix this > incompatibility by changing the field to optional. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
