hive一些问题

标签：hive一些问题

hive普通用户报错：

一、报错

Booting Derby (version The Apache Software Foundation - Apache Derby - 10.10.1.1 - (1458268)) instance a816c00e-0154-2ed3-cbb2-00000e1ebc98 

on database directory /var/lib/hive/metastore/metastore_db in READ ONLY mode with class loader sun.misc.Launcher$AppClassLoader@7cc355be. 

Loaded fromfile:/usr/hdp/2.2.0.0-2041/hive/lib/derby-10.10.1.1.jar.

问题：明显是metastore数据库read only，没有写权限

解决办法：

# cd /var/lib/hive/metastore/

# chmod -R a+w metastore_db/

二、报错如下，但是hive还是进来了

Booting Derby version The Apache Software Foundation - Apache Derby - 10.10.1.1 - (1458268): instance a816c00e-0154-3155-87b8-00000e0b5a08

hive> 

   > 

还是权限问题：/var/lib/hive# chown -R hive:hive metastore/

三、运行hive命令
