Haohui Mai created HDFS-6038: -------------------------------- Summary: JournalNode hardcodes NameNodeLayoutVersion in the edit log file Key: HDFS-6038 URL: https://issues.apache.org/jira/browse/HDFS-6038 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Haohui Mai
In HA setup, the JNs receive edit logs (blob) from the NN and write into edit log files. In order to write well-formed edit log files, the JNs prepend a header for each edit log file. The problem is that the JN hard-codes the version (i.e., {{NameNodeLayoutVersion}} in the edit log, therefore it generates incorrect edit logs when the newer release bumps the {{NameNodeLayoutVersion}} during rolling upgrade. -- This message was sent by Atlassian JIRA (v6.2#6252)
