Hadoop 2.6.0 HIVE 2.1.1配置

我用的hadoop 是2.6.0 版本，hive 是 2.1.1版本
进入；/home/zkpk/apache-hive-2.1.1-bin/
执行hive 后报错：

（1）Exception in thread "main" java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException:

java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

MetaException(message:Version information not found in metastore. )
Caused by: java.lang.RuntimeException: Unable to instantiate

org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

分析：需要在hive中首先启动 metastore:
使用：

apache-hive-2.1.1-bin/bin/hive --service metastore &

（2）然后报错：
message:Version information not found in metastore.

分析在hive配置中吧schema设置为不验证：

message:Version information not found in metastore. )”
修改conf/hive-site.xml 中的 “hive.metastore.schema.verification” 值为 false 即可解决 “Caused by: MetaException

(message:Version information not found in metastore. )”
<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
<description>
Enforce metastore schema version consistency.
True: Verify that version information stored in metastore matches with one from Hive jars. Also disable automatic
schema migration attempt. Users are required to manully migrate schema after Hive upgrade which ensures
proper metastore schema migration. (Default)
False: Warn if the version information stored in metastore doesn't match with one from in Hive jars.
</description>
</property>

3 执行hive.继续报错误：

MetaException(message: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))

分析：需要使用 schematool工具初始化hive的元素：

# 进入指定的目录
cd apache-hive-2.1.1-bin/bin/

# 初始化,如果是mysql则derby可以直接替换成mysql
./schematool -initSchema -dbType mysql

然后执行：[root@master bin]# hive
报错：: Permission denied: user=root, access=EXECUTE, inode="/tmp":zkpk:supergroup:drwx------
at org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkFsPermission(FSPermissionChecker.java:271)

分析：
我一直用zkpk用户部署hive，看来是权限不对

切换账户：
su zkpk
执行：:/home/zkpk/apache-hive-2.1.1-bin/bin/hive 正常启动：

hive> show tables;
OK
Time taken: 1.993 seconds
hive>
搞定；
