com.alimama.mdrill.editlog.write.FileJournalManager
org.apache.hadoop.hdfs.server.namenode.FileJournalManager
Journal manager for the common case of edits files being written to a storage directory. Note: this class is not thread-safe and should be externally synchronized.

Examples of com.alimama.mdrill.editlog.write.FileJournalManager

    journalSet = new JournalSet(1);

    }
    if (journalSet.isEmpty()) {
      LOG.error("No edits directories configured!");
