Hive安装配置过程中出现的错误

1、hive CLI启动时报错：（hadoop-2.6+ HIVE 1.2.0）：

Logging initialized using configuration in file:/disk2/hadoop/hive/conf/hive-log4j.properties
[ERROR] Terminal initialization failed; falling back to unsupported
java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected
原因：

根据文章： https://cwiki.apache.org/confluence/display/Hive/Hive+on+Spark%3A+Getting+Started

的说明：

Hive has upgraded to Jline2 but jline 0.9x exists in the Hadoop lib

，所以按以下步骤：

1. Delete jline from the Hadoop lib directory (it's only pulled in transitively from ZooKeeper).
2. export HADOOP_USER_CLASSPATH_FIRST=true

也有人说不需要删除jline jar，只需配置 HADOOP_USER_CLASSPATH_FIRST=true 就可以，经验证确实可以
