背景介绍
1.软件版本
- hive : hive-0.13.1
- spark : spark-1.2.0-bin-hadoop2.3
- hadoop : hadoop-2.2.0
- phoenix : phoenix-4.4.0-HBase-0.98
- hbase : hbase-0.98.0-hadoop2
2. 准备工作
- 保证hdfs可用
- 保证hive可用
3. 配置spark
3.1 设置SPARK_CLASSPATH
vi $SPARK_HOME/conf/spark-env.sh
export SPARK_CLASSPATH=$SPARK_CLASSPATH:/home/yarn/spark/lib/mysql-connector-java-5.1.17.jar:/home/yarn/hadoop-2.2.0/lib/*:/home/yarn/hbase-0.98.0-hadoop2/lib/hbase-protocol-0.98.0-hadoop2.jar
3.2 拷贝hdfs-site.xml hive-site.xml
cp $HADOOP_HOME/hdfs-site.xml $SPARK_HOME/conf/
cp $HIVE_HOME/conf/hive-site.xml $SPARK_HOME/conf/
4. 常见问题：
4.1. hive连接元数据报错
检查：mysql中hive的元数据字符集，hive要求元数据库字符集必须为：latin1
如果不是：使用以下命令修改字符集编码
alter database hive character set latin1;
ALTER TABLE hive.* DEFAULT CHARACTER SET latin1;
4.2.注意：spark.driver.extraClassPath和SPARK_CLASSPATH这两个设置同时存在一个
4.3. IllegalAccessError: class com.google.protobuf.ZeroCopyLiteralByteString cannot access its superclass com.google.protobuf.LiteralByteString
问题原因：
这个问题的发生是由于优化了HBASE-9867 引起的，无意间引进了一个依赖类加载器。
它影响使用-libjars参数和使用 fat jar两种模式的job.
fat jar模式Hadoop的一个特殊功能：
可以读取操作目录中/lib目录下包含的所有库的JAR文件，
把运行job依赖的jar放在jar中的lib目录下。
解决方案：
将hbase-protocol-0.98.0-hadoop2.jar加入SPARK_CLASSPATH中
4.4. MetaException(message:java.lang.ClassNotFoundException Class org.apache.phoenix.hive.PhoenixSerde
尝试方案：
- 将phoenix-hive-4.2.2-jar-with-dependencies.jar加入SPARK_CLASSPATH ==尝试结果：
失败== - 将phoenix-hive-4.2.2-jar-with-dependencies.jar设置到$SPARK_CLASSPATH/conf/hive-site.xml ==尝试结果：
失败==
最终解决方案：
在执行spark-sql或spark-shell时候加入参数：
--jars /home/yarn/hive/lib/phoenix-hive-4.2.2-jar-with-dependencies.jar
如下:
spark-sql --master spark://big147:7077 --executor-memory 20G --total-executor-cores 2 --jars /home/yarn/hive/lib/phoenix-hive-4.2.2-jar-with-dependencies.jar

解决方案：
方案1.
执行spark-sql或spark-shell加入参数 --driver-class-path执行驱动位置
spark-shell --master spark://big147:7077 --executor-memory 20G --total-executor-cores 2 --driver-class-path /home/yarn/hive/lib/mysql-connector-java-5.1.26.jar
方案2.
将驱动包加入SPARK_CLASSPATH:如下
vi $SPARK_HOME/conf/spark-env.sh
export SPARK_CLASSPATH=$SPARK_CLASSPATH:/home/yarn/hadoop-2.2.0/lib/*:/home/yarn/hbase-0.98.0-hadoop2/lib/hbase-protocol-0.98.0:/home/yarn/spark/lib/mysql-c
onnector-java-5.1.17.jar
