             Summary: Journal Nodes should refuse to format non-empty directories
                 Key: HDFS-11112
                 URL: https://issues.apache.org/jira/browse/HDFS-11112
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Arpit Agarwal


Journal Nodes should reject the {{format}} RPC request if a storage directory is non-empty. The relevant code is in {{JNStorage#format}}.

{code}
  void format(NamespaceInfo nsInfo) throws IOException {
    setStorageInfo(nsInfo);
...
    unlockAll();
    sd.clearDirectory();
    writeProperties(sd);
    createPaxosDir();
    analyzeStorage();
{code}

This would make the behavior similar to {{namenode -format -nonInteractive}}.
