hive命令行抛NullPointerException

我只是执行了一下这个代码

create temporary function strip as 'com.fatkun.Strip';

就抛出异常

hive> create temporary function strip as 'com.fatkun.Strip';
OK
Exception in thread "main" java.lang.NullPointerException
	at org.apache.hadoop.hive.cli.CliDriver.processCmd(CliDriver.java:221)
	at org.apache.hadoop.hive.cli.CliDriver.processLine(CliDriver.java:286)

从代码中看CliDriver.java:221,
原来和print header有关系。。。囧之前是为了打印header
默认这个是false的,所以把它去掉或者在hive-site置为false即可

<property>
  <name>hive.cli.print.header</name>
  <value>false</value>
</property>
