hive_异常_01_ Terminal initialization failed; falling back to unsupported

一、异常现象

hive初始化数据库时，在执行了

schematool  -initSchema -dbType mysql 

这个命令时，终端抛出如下异常：

[ray@rayner bin]$ schematool  -initSchema -dbType mysql

Metastore Connection Driver :    org.apache.derby.jdbc.EmbeddedDriver

二、异常原因

jar版本包冲突

Hadoop lib 下已经存在了 jline 0.9x ，但是在hive中将Jline升级到了Jline2。

启动hive的时候，由于hive依赖hadoop，启动hive，会将hadoop的配置以及jar包等等导入到hive中，导致jar包版本冲突。

三、异常解决

如上图：将hive的新版jline，替换hadoop的老版本即可。

注：hadoop中的jline所在目录为：

/developer/hadoop-2.6./share/hadoop/yarn/lib
