An error occurs when importing data using sqoop:

Exception in thread “main” java.lang.NoClassDefFoundError: jline/console/completer/ArgumentCompleter$ArgumentDelimiter

Caused by: java.lang.ClassNotFoundException: jline.console.completer.ArgumentCompleter$ArgumentDelimiter

Solution:
Hadoop cannot find the jline package. Go to the Lib directory of hive to find jline.jar, put it in/share/Hadoop/yarn/Lib in Hadoop, and then execute it.
