hive安装过程中的坑

启动报错

1、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

解决方法

hive.querylog.location

hive.exec.local.scratchdir

hive.downloaded.resources.dir

三个值写成绝对值

2、Found class jline.Terminal, but interface was expected

解决方法：hadoop目录下存在老版本jline，用新版本代替。

3、Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.SafeModeException): Cannot create directory /tmp/hive/root/0f671ef9-fe2e-48db-9019-c08145fe9f75. Name node is in safe mode.

解决方法：关闭hadoop安全模式，Hadoopdfsadmin -safemode leave
