Hypertable on HDFS(hadoop) 安装

Hadoop - HDFS 安装指南

过程 4.2. Hypertable on HDFS

1. 创建工作目录

   $ hadoop fs -mkdir /hypertable
   $ hadoop fs -chmod 777 /hypertable
   					

2. 安装 Java 运行环境

   yum install java-1.7.0-openjdk
   yum localinstall http://ftp.cuhk.edu.hk/pub/packages/apache.org/hadoop/common/hadoop-1.1.2/hadoop-1.1.2-1.x86_64.rpm
   					

3. 修改 jrun bug

   cp /opt/hypertable/current/bin/jrun /opt/hypertable/current/bin/jrun.old
   
   vim /opt/hypertable/current/bin/jrun
   #HT_JAR=`ls -1 /opt/hypertable/doug/current/lib/java/*.jar | grep "hypertable-[^-]*.jar" | awk 'BEGIN {FS="/"} {print $NF}'`
   HT_JAR=`ls -1 /opt/hypertable/current/lib/java/*.jar | grep "hypertable-[^-]*.jar" | awk 'BEGIN {FS="/"} {print $NF}'`
   					

    export JAVA_HOME=/usr
    export HADOOP_HOME=/usr
    export HYPERTABLE_HOME=/opt/hypertable/current
   					

4. hypertable.cfg

   # cat conf/hypertable.cfg
   #
   # hypertable.cfg
   #
   
   # HDFS Broker
   #HdfsBroker.Hadoop.ConfDir=/etc/hadoop/conf
   HdfsBroker.Hadoop.ConfDir=/etc/hadoop
   
   # Ceph Broker
   CephBroker.MonAddr=192.168.6.25:6789
   
   # Local Broker
   DfsBroker.Local.Root=fs/local
   
   # DFS Broker - for clients
   DfsBroker.Port=38030
   
   # Hyperspace
   Hyperspace.Replica.Host=localhost
   Hyperspace.Replica.Port=38040
   Hyperspace.Replica.Dir=hyperspace
   
   # Hypertable.Master
   #Hypertable.Master.Host=localhost
   Hypertable.Master.Port=38050
   
   # Hypertable.RangeServer
   Hypertable.RangeServer.Port=38060
   
   Hyperspace.KeepAlive.Interval=30000
   Hyperspace.Lease.Interval=1000000
   Hyperspace.GracePeriod=200000
   
   # ThriftBroker
   ThriftBroker.Port=38080
   					

   /etc/hadoop/hdfs-site.xml

   					
   # cat /etc/hadoop/hdfs-site.xml
   <?xml version="1.0"?>
   <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
   
   <!-- Put site-specific property overrides in this file. -->
   
   <configuration>
       <property>
           <name>dfs.name.dir</name>
           <value>/var/hadoop/name1</value>
           <description>  </description>
       </property>
       <property>
           <name>dfs.data.dir</name>
           <value>/var/hadoop/hdfs/data1</value>
           <description> </description>
       </property>
       <property>
           <name>dfs.replication</name>
           <value>2</value>
       </property>
   </configuration>
   					
   					

5. 启动 dfsbroker

   # /opt/hypertable/current/bin/set-hadoop-distro.sh cdh4
   Hypertable successfully configured for Hadoop cdh4
   					

   # /opt/hypertable/current/bin/start-dfsbroker.sh hadoop
   DFS broker: available file descriptors: 1024
   Started DFS Broker (hadoop)
   					

   查看启动日志

   # tail -f /opt/hypertable/current/log/DfsBroker.hadoop.log
   log4j:WARN No appenders could be found for logger (org.apache.hadoop.conf.Configuration).
   log4j:WARN Please initialize the log4j system properly.
   HdfsBroker.dfs.client.read.shortcircuit=false
   HdfsBroker.dfs.replication=2
   HdfsBroker.Server.fs.default.name=hdfs://namenode.example.com:9000
