Hadoop2.7實戰v1.0之Hive-2.0.0+MySQL本地模式安裝

hackeruncle發表於2016-04-03
HadoopHiveMySql模式
已有環境:Hadoop-2.7.2+zookeeper-3.4.6完全分散式環境搭建(HDFS、YARN HA)
Active namenode:sht-sgmhadoopnn-01
Hive服務端客戶端、後設資料庫mysql部署在 active namenode機器上
User:hive
Database:hive_local_meta

1.Install MySQL5.6.23
2.Create db and user
sht-sgmhadoopnn-01:mysqladmin:/usr/local/mysql:>mysql -uroot -p
mysql> create database hive_local_meta;
Query OK, 1 row affected (0.04 sec)

mysql> create user 'hive' identified by 'hive';
Query OK, 0 rows affected (0.05 sec)

mysql> grant all privileges on hive_local_meta.* to 'hive'@'%';
Query OK, 0 rows affected (0.03 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

3.Install hive-2.0.0
[root@sht-sgmhadoopnn-01 tmp]# wget

[root@sht-sgmhadoopnn-01 tmp]# tar zxvf apache-hive-2.0.0-bin.tar.gz
[root@sht-sgmhadoopnn-01 tmp]# mv apache-hive-2.0.0-bin /hadoop/hive
[root@sht-sgmhadoopnn-01 tmp]# cd /hadoop/hive

7.第一次執行  bin/hive 客戶端
[root@sht-sgmhadoopnn-01 hive-2.0.0]# cd bin
[root@sht-sgmhadoopnn-01 bin]# hive
Logging initialized using configuration in jar:file:/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Exception in thread "main" java.lang.RuntimeException: Hive metastore database is not initialized. Please use schematool (e.g. ./schematool -initSchema -dbType ...) to create the schema. If needed, don't forget to include the option to auto-create the underlying database in your JDBC connection string (e.g. ?createDatabaseIfNotExist=true for mysql)

8.初始化 db
[root@sht-sgmhadoopnn-01 bin]# schematool -initSchema -dbType mysql
Metastore connection URL:        jdbc:mysql://localhost/hive?createDatabaseIfNotExist=true
Metastore Connection Driver :    com.mysql.jdbc.Driver
Metastore connection User:       hive
Starting metastore schema initialization to 2.0.0
Initialization script hive-schema-2.0.0.mysql.sql
Initialization script completed
schemaTool completed
You have mail in /var/spool/mail/root
[root@sht-sgmhadoopnn-01 bin]#

9.檢視MySQL後設資料,show tables
sht-sgmhadoopnn-01.telenav.cn:mysqladmin:/usr/local/mysql:>mysql -uhive -p
mysql> use hive;
Database changed

mysql> show tables;
+---------------------------+
| Tables_in_hive            |
+---------------------------+
| aux_table                 |
| bucketing_cols            |
...............
...............
| tbls                      |
| txn_components            |
| txns                      |
| type_fields               |
| types                     |
| version                   |
+---------------------------+
55 rows in set (0.00 sec)

10.測試,建立表,插入資料
## "tab製表符"分隔
[root@sht-sgmhadoopnn-01 conf]# vi /tmp/studentInfo.txt
1       a       26      110
2       b       29      120
~

[root@sht-sgmhadoopnn-01 bin]# hive
Logging initialized using configuration in jar:file:/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
hive> create table studentinfo (id int,name string, age int,tel string)
   > row format delimited  fields terminated by '\t'
   > stored as textfile;
OK
Time taken: 2.347 seconds
hive> load data local inpath '/tmp/studentInfo.txt'  into table studentinfo;
Loading data to table default.studentinfo
OK
Time taken: 1.383 seconds
hive> select * from studentinfo;
OK
1       a       26      110
2       b       29      120
Time taken: 0.173 seconds, Fetched: 2 row(s)
hive> exit();

11.再次修改兩個引數
# "hdfs://mycluster"是指$HADOOP_HOME/etc/hadoop/core-site.xml檔案的fs.defaultFS的值(NameNode HA URI)

點選(此處)摺疊或開啟

  1. [root@sht-sgmhadoopnn-01 conf]# vi hive-site.xml
  2.       <property>
  3.      <name>hive.metastore.warehouse.dir</name>
  4.      <value>hdfs://mycluster/user/hive_local/warehouse</value>
  5.       </property>

  7.     <property>
  8.         <name>javax.jdo.option.ConnectionURL</name>
  9.         <value>jdbc:mysql://sht-sgmhadoopnn-01:3306/hive_local_meta?createDatabaseIfNotExist=true</value>
  10.         <description>JDBC connect string for a JDBC metastore</description>
  11.     </property>
11.再次驗證修改的內容，是否成功建立classInfo表
[root@sht-sgmhadoopnn-01 bin]# hive
Logging initialized using configuration in jar:file:/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
hive> create table classInfo(id int,classname string,stucount int) row format delimited  fields terminated by '\t'
   > stored as textfile;
OK
Time taken: 2.257 seconds
