http://hive.apache.org/downloads.html 上有說明,hadoop3.x版本須要hive3.0.0,而hadoop2.x須要hive2.3.3。由於個人hadoop是2.9,因此選擇下載hive2.3.3。Hive是hadoop的工具,因此只須要安裝在NameNode上,不須要安裝在DataNode上。html
Hadoop 安裝請移步java

Hive環境模式有3中,本例中採用了內嵌模式
cp hive-default.xml.template hive-site.xml數據庫
hive-site.xml 文件內容不須要修改,主要配置apache
<property> <name>hive.metastore.warehouse.dir</name> <value>/user/hive/warehouse</value> <description>location of default database for the warehouse</description> </property> .. <property> <name>hive.exec.scratchdir</name> <value>/tmp/hive</value> <description>HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/<username> is created, with ${hive.scratch.dir.permission}.</description> </property>
注:ubuntu
hive.metastore.warehouse.dir緩存
該參數指定了Hive的數據存儲目錄,默認位置在HDFS上面的 /user/hive/warehouse路徑下bash
hive.exec.scratchdirsession
該參數指定了Hive的數據臨時文件目錄,默認位置爲HDFS上面的 /tmp/hive路徑下jvm
hive-site.xml 文件中有兩個重要的HDFS路徑/user/hive/warehouse和/tmp/hive,須要在HDFS中建立,並修改權限
hadoop fs -mkdir /user hadoop fs -mkdir /user/hive hadoop fs -mkdir /user/hive/warehouse hadoop fs -mkdir /tmp/hive hadoop fs -chmod 777 /user/hive/warehouse hadoop fs -chmod 777 /tmp/hive
內嵌模式用的是本地數據庫derby

A1:
在hive-site.xml文件最前面增長以下配置,重啓hive
建立一個緩存目錄:mkdir -p /usr/local/apache-hive-2.3.3-bin/tmpdir
<property> <name>system:java.io.tmpdir</name> <value>/usr/local/apache-hive-2.3.3-bin/tmpdir</value> </property> <property> <name>system:user.name</name> <value>hive</value> </property>
