Try running this code in the Spark shell.  It may produce different topics each time (since LDA includes some randomization), but it should give topics similar to those listed above.

<<Hive编程指南>>读书笔记

1. 设置hive以本地模式运行(即使当前用户是在分布式模式或伪分布式模式下执行也使用这种模式)

set hive.exec.model.local.auto=true;

若想默认使用这个配置,可以将这个命令添加到$HOME/.hiverc文件中
