List of rollEditLog() Examples

Examples of rollEditLog()

org.apache.hadoop.hdfs.DistributedFileSystem.rollEditLog()
Rolls edit log at the namenode manually.
org.apache.hadoop.hdfs.server.protocol.NamenodeProtocol.rollEditLog()
Closes the current edit log and opens a new one. The call fails if the file system is in SafeMode. @throws IOException @return a unique token to identify this transaction.
org.apache.hadoop.hdfs.server.protocol.NamenodeProtocols.rollEditLog()

Examples of org.apache.hadoop.hdfs.server.protocol.NamenodeProtocols.rollEditLog()

          new File(sd1.getCurrentDir(), NNStorage.getImageFileName(2)));
      
      // Restore the good dir
      currentDir.setExecutable(true);
      nn.restoreFailedStorage("true");
      nn.rollEditLog();


      // Checkpoint again -- this should upload to both dirs
      secondary.doCheckpoint();
