hive一些问题
hadoop client/hive client去连接 微软云Azure上的HDI报错：
hive --service metastore
Exception in thread "main" org.apache.thrift.transport.TTransportException: Could not create ServerSocket on address 0.0.0.0/0.0.0.0:9083.
Getting MissingTableException: Required table missing VERSION when starting hive on mysql
根本原因是这里使用的是HDI
1、这两个配置文件都改（centos和ubuntu有区别）
# vim /usr/hdp/2.2.0.0-2041/hive/conf/hive-site.xml
# vim /etc/hive/conf/hive-site.xml
hive.metastore.warehouse.dir /hive/warehouse location of default database for the warehouse hive.metastore.uris thrift://headnodehost:9083 Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.
2、修改hosts
vim /etc/hosts
内容是来自于HDI的windows机器上的配置
10.0.2.7 headnodehost # SlaveNodeManager 10.0.2.7 jobtrackerhost # SlaveNodeManager 10.0.2.7 namenodehost # SlaveNodeManager
hive普通用户报错：
1、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/
2、报错如下，但是hive还是进来了

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