无法在Mac上使用mysql启动Hive

Question

我以前在使用macOS 10.12.3上的本地开发环境将Mysql升级到Hive时遇到了一些麻烦，因为我以前使用了本地derby元存储。

每当我启动配置单元时，都会出现以下异常：

Hive是2.10版，而Hadoop是2.7.3版。 namenode和datanode都已启动，mysql也已启动，包括正确初始化的metastore数据库。

环境变量的设置如下：

➜  ~ echo $HADOOP_HOME
/usr/local/Cellar/hadoop/2.7.3
➜  ~ echo $HIVE_HOME
/usr/local/Cellar/hive/2.1.0
➜  ~ echo $PATH
/usr/local/Cellar/hadoop/2.7.3/bin:/usr/local/Cellar/spark-2.0.0-bin-hadoop2.7:/usr/local/Cellar/hbase/1.2.2:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/MacGPG2/bin:/Users/christian/bin:/usr/local/Cellar/hive/2.1.0/bin

正常的HDFS操作工作：

➜  ~ hdfs dfs -ls /
17/02/26 18:54:44 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

让我们假装这不是一个问题，而是一个知识库/知识共享文章。

事实证明，我的Hive安装程序将hadoop-commons-2.6.0作为lib：

➜  lib pwd
/usr/local/Cellar/hive/2.1.0/libexec/lib
➜  lib ll | grep hadoop-common
-rw-r--r--  1 christian  admin   3.1M Sep  3 07:29 hadoop-common-2.6.0.jar

但是该方法是在2.7.3中添加的，请参见source 。

因此，替换该库即可。 我不知道我是如何做到的。
