一. HBase环境搭建
1. 编辑/opt/hbase-1.3.1/conf/hbase-env.sh,如下所示:
export JAVA_HOME=/usr/local/jdk1.8.0_141 export HBASE_HOME=/opt/hbase-1.3.1 export HBASE_LOG_DIR=/home/ssw/Data/hbase-logs export HBASE_MANAGES_ZK=true2. 编辑 /opt/hbase-1.3.1/conf/hbase-site.xml,如下所示:
<configuration> <property> <name>hbase.rootdir</name> <value>hdfs://master:9000/hbase</value> </property> <property> <name>hbase.cluster.distributed</name> <value>true</value> </property> <property> <name>hbase.master</name> <value>master:60000</value> </property> <property> <name>hbase.zookeeper.quorum</name> <value>master,slave1,slave2</value> </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/home/ssw/Data/zookeeper</value> </property> </configuration>3. 编辑 /opt/hbase-1.3.1/conf/regionservers,如下所示:
Slave1 Slave24. 启动HBase集群
/opt/hbase-1.3.1/bin/start-hbase.sh5. 查看集群是否启动成功
Master:HQuorumPeer;HMaster。Slave:HQuorumPeer;HRegionServer。
二. Hive环境搭建
1. 安装MysqL
wget http://repo.MysqL.com/MysqL-community-release-el7-5.noarch.rpm sudo rpm -ivh MysqL-community-release-el7-5.noarch.rpm sudo yum install MysqL-server sudo chown -R root:root /var/lib/MysqL service MysqLd restart $ MysqL -u root MysqL > use MysqL; MysqL > update user set password=password('root') where user='root'; MysqL > exit; service MysqLd restart2. 为Hive建立相应的MysqL账户,并赋予足够的权限,如下所示:
create user 'hive' identified by 'MysqL'; grant all privileges on *.* to 'hive'@'%' with grant option; flush privileges; service MysqLd restart
3.建立Hive专用元数据库,用创建的hive账号登录,如下所示:
MysqL -uhive -p'MysqL' MysqL> create database hive;
4.加载MysqL驱动包
将MysqL-connector-java-5.1.44-bin.jar放$HIVE_HOME$/lib目录下面。
5. 编辑/etc/profile,如下所示:
export HIVE_HOME=/opt/hive-2.3.0 export PATH=$PATH:$HIVE_HOME/bin
6. 编辑hive-config.sh,如下所示:
export JAVA_HOME=/usr/local/jdk1.8.0_141 export HIVE_HOME=/opt/hive-2.3.0 export HADOOP_HOME=/opt/hadoop-2.7.37. 编辑hive-site.xml,如下所示:
<property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:MysqL://localhost:3306/hive?createDatabaseIfNotExist=true</value> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.MysqL.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hive</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>MysqL</value> </property>8. 编辑hive-env.sh,如下所示:
export HOME==/opt/hadoop-2.7.3 export HIVE_CONF_DIR=/opt/hive-2.3.0/conf export HIVE_AUX_JARS_PATH=/opt/hive-2.3.0/lib
9.验证Hive配置是否成功,如下所示:
hive> create table test_table (id int,name string,no int); MysqL -uhive -p'MysqL'; show databases; use hive; show tables; select * from TBLS;
说明:Hive将元数据库存储在MysqL中,元数据包括表的名字,表的列和分区及其属性,表的属性(是否为外部表
等),表的数据所在目录。
三. Kylin环境搭建
四. ZooKeeper环境搭建
五. Kafka环境搭建
六. 遇到的问题
1.create directory /tmp/hive/XXX. Name node is in safe mode.
解析:hdfs dfsadmin -safemode leave
2.Failed: SemanticException org.apache.hadoop.hive.ql.Metadata.HiveException: java.lang.RuntimeException:
Unable to instantiate org.apache.hadoop.hive.ql.Metadata.SessionHiveMetaStoreClient.
解析:用hive -hiveconf hive.root.logger=DEBUG,console排查问题。
3.org.apache.hadoop.hive.Metastore.api.MetaException: Version information not found in Metastore.
