Ubuntu 14.10 下Hive配置

1 系统环境

Ubuntu 14.10

JDK-7

Hadoop 2.6.0

2 安装步骤

2.1 下载Hive

我第一次安装的时候，下载的是Hive-1.2.1，配置好之后，总是报错

[ERROR] Terminal initialization failed; falling back to unsupported

对于这个错误，很多人的做法都是将hadoop/share/hadoop/yarn/lib中的jline 替换成高版本的，如hive中的2.×

1.Delete jline from the Hadoop lib directory (it's only pulled in transitively from ZooKeeper).
2.export HADOOP_USER_CLASSPATH_FIRST=true

但是我替换之后，还是报错，后来换了一个低版本的HIve-1.0.1，就好了，所以如果出现如上错误，不一定非的是jar问题，也可能是版本问题。

2.2 配置hive

2.2.1 拷贝一份hive-env.sh，设置HADOOP_HOME

2.2.2 拷贝一份hive-site.xml

主要修改如下参数

<property>
   <name>javax.jdo.option.ConnectionURL </name>
   <value>jdbc:mysql://localhost:3306/hive </value>
</property> 

<property>
   <name>javax.jdo.option.ConnectionDriverName </name>
   <value>com.mysql.jdbc.Driver </value>
</property>

<property>
   <name>javax.jdo.option.ConnectionPassword </name>
   <value>hive </value>
</property> 

<property>
   <name>hive.hwi.listen.port </name>
   <value>10000</value>
   <description>This is the port the Hive Web Interface will listen on </descript ion>
</property> 

<property>
   <name>datanucleus.autoCreateSchema </name>
   <value>true</value>
</property> 

<property>
   <name>datanucleus.fixedDatastore </name>
   <value>false</value>
</property>
</property> 

  <property>
    <name>javax.jdo.option.ConnectionUserName</name>
    <value>hive</value>
    <description>Username to use against metastore database</description>
  </property>

  <property>
    <name>hive.exec.local.scratchdir</name>
    <value>/home/hdpsrc/hive/iotmp</value>
    <description>Local scratch space for Hive jobs</description>
  </property>
  <property>
    <name>hive.downloaded.resources.dir</name>
    <value>/home/hdpsrc/hive/iotmp</value>
    <description>Temporary local directory for added resources in the remote file system.</description>
  </property>
  <property>
    <name>hive.querylog.location</name>
    <value>/home/hdpsrc/hive/iotmp</value>
    <description>Location of Hive run time structured log file</description>
  </property> 

2.3 拷贝一份hive-log4j.properties

这里我只是设置了log文件的路径

2.4 建立相关文件夹，就是在2.2中设置的

2.5 在HDFS中建立相关文件夹

  $ $HADOOP_HOME/bin/hadoop fs -mkdir       /tmp
  $ $HADOOP_HOME/bin/hadoop fs -mkdir       /user/hive/warehouse
  $ $HADOOP_HOME/bin/hadoop fs -chmod g+w   /tmp
  $ $HADOOP_HOME/bin/hadoop fs -chmod g+w   /user/hive/warehouse 

2.3 安装MySQL

因为这里的关系型数据库是用的mysql，那么需要安装mysql，同时按照上面配置的新建hive用户，新建数据库。

安装mysql参考：http://www.cnblogs.com/liuchangchun/p/4099003.html

新建用户参考：http://www.cnblogs.com/liuchangchun/p/4431426.html

因为之前安装mysql后将编码设置成了utf8的，在启动hive的时候报了如下错：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 767 bytes

这个错误，需要修改hive数据库的编码：

alter database hive character set latin1;

2.4 拷贝mysql的驱动jar包到hive/lib下面

如果不拷贝，那么会报错：找不到jar包

Caused by: org.datanucleus.store.rdbms.connectionpool.DatastoreDriverNotFoundException: The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.

    at org.datanucleus.store.rdbms.ConnectionFactoryImpl.generateDataSources(ConnectionFactoryImpl.java:238)
    ... 67 more

2.5 启动hive

启动之前要确保hdfs已经起来。

在命令行执行：hive，即可进入hive命令行界面，如果没有错误，恭喜你，OK了。

如果HDFS没起来，那么可能报错.。。

2.6 启动hwi WEB客户端

hive提供了几种交互方式，有命令行，还有web界面的。如果要启动web服务，可以通过如下命令

hive --service hwi

但是之前需要设置一些属性

<property>
    <name>hive.hwi.listen.host</name>
    <value>192.168.1.102</value>
    <description>This is the host address the Hive Web Interface will listen on</description>
  </property>
  <property>
    <name>hive.hwi.listen.port</name>
    <value>10000</value>
    <description>This is the port the Hive Web Interface will listen on</description>
  </property>
  <property>
    <name>hive.hwi.war.file</name>
    <value>lib/hive-hwi-1.0.1.war</value>
    <description>This sets the path to the HWI war file, relative to ${HIVE_HOME}. </description>
  </property>

启动之后，进入http://hostname:10000/hwi/。但是，我这里遇到了几个问题

a. 找不到war包

ls: cannot access /home/grid2/apache-hive-0.13.1-bin/lib/hive-hwi-*.war: No such file or directory
14/09/14 21:07:10 INFO hwi.HWIServer: HWI is starting up
14/09/14 21:07:11 WARN conf.HiveConf: DEPRECATED: Configuration property hive.metastore.local no longer has any effect. Make sure to provide a valid value for hive.metastore.uris if you are connecting to a remote metastore.
14/09/14 21:07:11 WARN conf.HiveConf: DEPRECATED: hive.metastore.ds.retry.* no longer has any effect.  Use hive.hmshandler.retry.* instead
14/09/14 21:07:11 FATAL hwi.HWIServer: HWI WAR file not found at /home/grid2/apache-hive-0.13.1-bin/lib/hive-hwi-@VERSION@.war

因为在hive/lib下面确实没有hive-hwi-*.war包，那我们可以自己下载hive的源码，然后打包成war放大hive/lib下面。

b. 启动hwi后没有错误，但是访问http://hostname:10000/hwi/就会报错

15/08/27 14:13:40 ERROR mortbay.log: /hwi/
java.lang.IllegalStateException: No Java compiler available

    at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:315)
    …………………………………………………………………………

这个问题目前没解决o(╯□╰)o，我的替代方案是使用HUE

a. HUE中配置HIVE

找到beeswax标签，不叫hive，配置如下属性，其中端口号要和hive-site.xml中的保持一致

hive-site.xml中配置thrift端口号

<property>
    <name>hive.server2.thrift.port</name>
    <value>19999</value>
    <description>Port number of HiveServer2 Thrift interface when hive.server2.transport.mode is 'binary'.</description>
  </property>

hive_server_host=192.168.1.102

# Port where HiveServer2 Thrift server runs on.
hive_server_port=19999

# Hive configuration directory, where hive-site.xml is located
hive_conf_dir=/home/hadoop/software/cloud/apache-hive-1.0.1-bin/conf

使用hue之前需要先启动hive thrift server

hive --service hiveserver2

我这里配置好之后遇到一个错误，费了好大劲才找到问题所在

如上错误，访问错误，我找到com.google.common.base.Stopwatch这个类的jar包，是guava.jar，这个jar包在hadoop和hive中都有，版本是11.0.2，同时我在JAVA_HOME中也有一个在jre/lib/ext中，但是版本是18.0(这个估计是我当时安装ambari时候放进去的，因为一个问题，要将guava换成最新版)，这样估计造成了版本不一致，所以出现了如上的错误。解决办法就是删了那个jar包，或是换成11.02，所以这里也要考虑一个程序加载顺序。
