zookeeper单机多实例
其实就是跑多个zk服务，以zkServer1为例，配置如下：其中192.168.29.128为虚拟机ip 很重要

dataDir=/virgil/zooserver/server1/data
dataLogDir=/virgil/zooserver/server1/logs
clientPort=2181
server.1=192.168.29.128:2888:3888
server.2=192.168.29.128:2889:3889
server.3=192.168.29.128:2890:3890

其余实例只需要保证clientPort，dataDir，dataLogDir，不一样即可
hadoop关键配置
写在前面：配置时最好写具体的ip，不要用localhost或者127.0.0.1，不然本地机器访问不到虚拟机
core-site.xml配置

    <property><name>hadoop.tmp.dir</name><value>file:/virgil/hadoop/tmp</value><description>Abase for other temporary directories.</description></property><property><name>fs.defaultFS</name><value>hdfs://192.168.29.128:9000/hbase</value></property>

hdfs-site.xml配置

    <property><name>dfs.replication</name><value>1</value></property><property><name>dfs.namenode.name.dir</name><value>file:/virgil/hadoop/tmp/dfs/name</value></property><property><name>dfs.datanode.data.dir</name><value>file:/virgil/hadoop/tmp/dfs/data</value></property>

hbase配置
hbase-site.xml配置

    <property><name>hbase.cluster.distributed</name><value>true</value></property><property><name>hbase.master.info.port</name><value>60010</value></property><property><name>hbase.rootdir</name><value>hdfs://192.168.29.128:9000/hbase</value></property><property><name>hbase.zookeeper.property.dataDir</name><value>/virgil/zooserver/data</value></property><property><name>hbase.zookeeper.quorum</name><value>192.168.29.128</value></property><property><name>hbase.zookeeper.property.clientPort</name><value>2181</value></property><property><name>hbase.zookeeper.property.dataDir</name><value>/virgil/zooserver/data</value></property>

java API访问位于虚拟机中的hbase
依次启动zookeeper、hadoop、hbase后

        Configuration HBASE_CONFIG = new Configuration();HBASE_CONFIG.set("hbase.zookeeper.quorum", "192.168.29.128");HBASE_CONFIG.set("hbase.zookeeper.property.clientPort", "2181");HBaseConfiguration cfg = new HBaseConfiguration(HBASE_CONFIG);HBaseAdmin admin = new HBaseAdmin(cfg);System.out.println(admin.tableExists("tableName"));
