Hive History Comman不起作用

Question

嗨，我是Hadoop Hive中的基本学习者。$ home/.hive History不起作用，或者让我知道在哪里输入该命令。我由于某些原因关闭了我的终端，并在此之后打开某个时间。现在如何打开以前的命令历史记录。请帮助我。我无法整理一下。

Answer 1

.hivehistory位于调用CLI的用户的主目录下方，例如 -

使用用户cloudera调用(我当前正在使用的用户(

bash-4.1$ ls -l ~/.hivehistory 
-rw-rw-r-- 1 cloudera cloudera 1093 May  6 10:42 /home/cloudera/.hivehistory

使用用户hive

调用时

bash-4.1$ ls -l ~hive/.hivehistory 
-rw-r--r-- 1 hive hive 20 May  6 10:53 /var/lib/hive/.hivehistory

源代码：clidriver.java

  private void setupCmdHistory() {
    final String HISTORYFILE = ".hivehistory";
    String historyDirectory = System.getProperty("user.home");
    PersistentHistory history = null;
    try {
      if ((new File(historyDirectory)).exists()) {
        String historyFile = historyDirectory + File.separator + HISTORYFILE;
        history = new FileHistory(new File(historyFile));
        reader.setHistory(history);
      } else {
        System.err.println("WARNING: Directory for Hive history file: " + historyDirectory +
                           " does not exist.   History will not be available during this session.");
      }
    } catch (Exception e) {
      System.err.println("WARNING: Encountered an error while trying to initialize Hive's " +
                         "history file.  History will not be available during this session.");
      System.err.println(e.getMessage());
    }
