hive一些問題

hadoop client/hive client去連接 微軟云Azure上的HDI報錯：

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

根本原因是這里使用的是HDI

1、這兩個配置文件都改（centos和ubuntu有區別）

# vim /usr/hdp/2.2.0.0-2041/hive/conf/hive-site.xml

# vim /etc/hive/conf/hive-site.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration supports_final="true">
<!-- Hive Configuration can either be stored in this file or in the hadoop configuration files
 that are implied by Hadoop setup variables.                               Aside from Hadoop setup variables - this file is provided as a convenience so that Hive
 users do not have to edit hadoop configuration files (that may be managed as a centralized 
 resource).    
-->
<property>
    <name>hive.metastore.warehouse.dir</name>
    <value>/hive/warehouse</value>
    <description>location of default database for the warehouse</description>
  </property>
  <property>
   <name>hive.metastore.uris</name>
    <value>thrift://headnodehost:9083</value>
    <description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description>
  </property>
</configuration>

2、修改hosts

vim /etc/hosts

內容是來自于HDI的windows機器上的配置

 10.0.2.7        headnodehost    # SlaveNodeManager
 10.0.2.7        jobtrackerhost  # SlaveNodeManager
 10.0.2.7        namenodehost    # SlaveNodeManager

hive普通用戶報錯：

1、報錯

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.

問題：明顯是metastore數據庫read only，沒有寫權限

解決辦法：

# cd /var/lib/hive/metastore/

# chmod -R a+w metastore_db/

2、報錯如下，但是hive還是進來了

還是權限問題：/var/lib/hive# chown -R hive:hive metastore/
