环境：
Linux: 
    Red Hat Enterprise Linux Server release 6.0 (Santiago)
Java: 
    java version "1.7.0_60"
    Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
    Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
Hadoop: 
    hadoop-2.6.0
Hive:
    apache-hive-1.2.0-bin


前提条件：
    gpmaster启动metastore服务：
[hadoop@gpmaster ~]$ nohup hive --service metastore > metastore.log 2>&1 &
    [1] 3937
[hadoop@gpmaster ~]$ netstat -nlt | grep 9083
    tcp        0      0 0.0.0.0:9083                0.0.0.0:*                   LISTEN 
可以看到metastore服务已经启动。


测试: 
    Hive客户端gpseg(192.168.1.129)通过metastore去访问gpmaster(192.168.1.128)节点的Hive元数据


结果：
[hadoop@gpseg apache-hive-1.2.0-bin]$ bin/hive

解决办法:
    首先查看Hadoop和Hive的jline版本:
    [hadoop@gpseg ~]$ find ./ -name jline*
    ./hadoop-2.6.0/share/hadoop/yarn/lib/jline-0.9.94.jar
    ./hadoop-2.6.0/share/hadoop/httpfs/tomcat/webapps/webhdfs/WEB-INF/lib/jline-0.9.94.jar
    ./hadoop-2.6.0/share/hadoop/kms/tomcat/webapps/kms/WEB-INF/lib/jline-0.9.94.jar
    ./apache-hive-1.2.0-bin/lib/jline-2.12.jar
    我们发现Hive的jline和Hadoop的不一致，所以需要将Hive的jline拷贝到Hadoop目录下面：
    [hadoop@gpseg ~]$ cp apache-hive-1.2.0-bin/lib/jline-2.12.jar hadoop-2.6.0/share/hadoop/yarn/lib/
[hadoop@gpseg ~]$ cd apache-hive-1.2.0-bin/
[hadoop@gpseg apache-hive-1.2.0-bin]$ bin/hive
