Hive 1.2.1源码编译依赖的Hadoop版本必须最少是2.6.0，因为里面用到了Hadoop的org.apache.hadoop.crypto.key.KeyProvider和org.apache.hadoop.crypto.key.KeyProviderFactory两个类，而这两个类在Hadoop 2.6.0才出现，否者会出现以下编译错误：

[ERROR] /home/q/spark/apache-hive-1.2.1-src/shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java:[43,36] package org.apache.hadoop.crypto.key does not exis
[ERROR] /home/q/spark/apache-hive-1.2.1-src/shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java:[41,36] package org.apache.hadoop.crypto.key does not exist
[ERROR] /home/q/spark/apache-hive-1.2.1-src/shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java:[42,48] package org.apache.hadoop.crypto.key.KeyProvider does not exist

　　Hive 1.2.1默认的Hadoop版本是2.6.0（2.6.0），不修改就行。

　　Hive 1.2.1依赖的Spark版本最高只能是Spark 1.4.1，如果你修改到Spark 1.5.x版本编译的时候会出现以下错误：

[ERROR] /home/q/spark/apache-hive-1.2.1-src/spark-client/src/main/java/org/apache/hive/spark/client/RemoteDriver.java:[441,11] org.apache.hive.spark.client.RemoteDriver.ClientListener is not abstract and does not override abstract method onBlockUpdated(org.apache.spark.scheduler.SparkListenerBlockUpdated) in org.apache.spark.scheduler.SparkListener

spark 1.2.1默认的Spark版本是1.3.1，1.3.1。如果没有特殊情况，不修改pom.xml文件即可一次性编译成功。

编译的时候需要按照配置好Maven，如果在编译时出现类似的内存不够问题，请设置如下配置

export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

上面弄完之后，我们可以用下面命令编译：

mvn clean package -Phadoop-2 -DskipTests

如果一切顺利的话，可以得到以下的编译结果：

编译时长根据你网络环境，最好配置成公司的Maven仓库。当然，如果你需要将编译好的文件进行打包，可以运行下面的命令：

mvn clean package -Phadoop-2 -DskipTests -Pdist

上面的命令运行完成之后，会在$HIVE_SRC/packaging/target目录下产生以下几个文件：
