1，首先需要安装hive，参考http://lqding.blog.51cto.com/9123978/1750967

2，在spark的配置目录下添加配置文件，让Spark可以访问hive的metastore。
root@spark-master:/usr/local/spark/spark-1.6.0-bin-hadoop2.6/conf# vi hive-site.xml
hive.metastore.uris
thrift://spark-master:9083
Thrift uri for the remote metastore. Used by metastore client to connect to remote metastore.
3，将MySQL jdbc驱动copy到spark的lib目录下
root@spark-master:/usr/local/hive/apache-hive-1.2.1/lib# cp mysql-connector-java-5.1.36-bin.jar /usr/local/spark/spark-1.6.0-bin-hadoop2.6/lib/
4，启动Hive的metastore服务
root@spark-master:/usr/local/hive/apache-hive-1.2.1/bin# ./hive --service metastore &
[1] 20518
root@spark-master:/usr/local/hive/apache-hive-1.2.1/bin# SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/hadoop/hadoop-2.6.0/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/local/spark/spark-1.6.0-bin-hadoop2.6/lib/spark-assembly-1.6.0-hadoop2.6.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
Starting Hive Metastore Server

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
5，启动spark-shell
root@spark-master:/usr/local/spark/spark-1.6.0-bin-hadoop2.6/bin# ./spark-shell --master spark://spark-master:7077
生成hiveContext
scala> val hc = new org.apache.spark.sql.hive.HiveContext(sc);
执行sql
scala> hc.sql("show tables").collect.foreach(println)
[sougou,false]
[t1,false]
scala> hc.sql("select count(*) from sougou").collect.foreach(println)

[1000000]跟Hive相比，速度是有所提升的。如果是复杂的语句，相比hive速度将更加的快。
