原因是hadoop目录下存在老版本jline：
/hadoop-2.5.2/share/hadoop/yarn/lib：
-rw-r--r-- 1 root root   87325 Mar 10 18:10 jline-0.9.94.jar

解决方法是：
将hive下的新版本jline的JAR包拷贝到hadoop下：
cp /hive/apache-hive-1.1.0-bin/lib/jline-2.12.jar ./

/hadoop-2.5.2/share/hadoop/yarn/lib：
-rw-r--r-- 1 root root   87325 Mar 10 18:10 jline-0.9.94.jar.bak
-rw-r--r-- 1 root root  213854 Mar 11 22:22 jline-2.12.jar

hive cli启动成功：
root@ubuntu:/hive# hive

调试中出现java.io.tmpdir目录的问题

异常详情如下：
Exception in thread "main" java.lang.RuntimeException: java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D

解决方案如下：
1.查看hive-site.xml配置，会看到配置值含有"system:java.io.tmpdir"的配置项
2.新建文件夹/home/grid/hive-0.14.0-bin/iotmp
3.将含有"system:java.io.tmpdir"的配置项的值修改为如上地址
启动hive，成功！

hive内存不够用的问题

hive> select * from t_test where ds=20150323 limit 2;
OK
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

问题原因： hive堆内存默认为256M

这个问题的解决方法为：
修改/usr/lib/hive/bin/hive-config.sh文件 中
# Default to use 256MB 
export HADOOP_HEAPSIZE=${HADOOP_HEAPSIZE:-256}
将上面256调大就行

用户不对的错误

编写JDBC客户端程序连接hive时，出现报错：

从最终的错误信息来看：User: hadoop is not allowed to impersonate anonymous，意思是用户hadoop不允许伪装成anonymous（hive的默认用户，默认配置可以查看）。
