环境：Hadoop 2.6.0 + hive-0.14.0
问题出现的背景：在hive中建表 （建表语句如下），并且表的字段中有Map，Set,Collection等集合类型。
CREATE EXTERNAL TABLE agnes_app_hour(
start_id string,
current_time string,
app_name string,
app_version string,
app_store string,
send_time string,
letv_uid string,
app_run_id string,
start_from string,
props map<string,string>,
ip string,
server_time string)
PARTITIONED BY (
dt string,
hour string,
product string)
ROW FORMAT DELIMITED
COLLECTION ITEMS TERMINATED BY ','
MAP KEYS TERMINATED BY ':'
STORED AS RCFILE ;
执行hive语句，执行
hive - e "select count(1) from temp_agnes_app_hour ; "
提交map/reduce 到yarn时报出如下异常：

针对"native-lzo library not available" 异常即lzo安装的异常。
===========================================
####安装lzo的过程
1.验证安装环境（以root账户执行）：
yum -y install lzo-devel zlib-devel gcc autoconf automake libtool
2.安装LZO (以下以haodop用户执行)
wget http://www.oberhumer.com/opensource/lzo/download/lzo-2.06.tar.gz
tar -zxvf lzo-2.06.tar.gz
./configure -enable-shared -prefix=/usr/local/hadoop/lzo/
make && make test && make install
3.安装LZOP
wget http://www.lzop.org/download/lzop-1.03.tar.gz
tar -zxvf lzop-1.03.tar.gz
./configure -enable-shared -prefix=/usr/local/hadoop/lzop
make && make install
4.把lzop复制到/usr/bin/
ln -s /usr/local/hadoop/lzop/bin/lzop /usr/bin/lzop
5.测试lzop
lzop /home/hadoop/data/access_20131219.log
会在生成一个lzo后缀的压缩文件： /home/hadoop/data/access_20131219.log.lzo
2,3,4,5 可以使用如下脚本批量执行。
####安装Hadoop-LZO
1. 下载Hadoop-LZO源码，
hadoop-lzo：下载地址
https://github.com/twitter/hadoop-lzo
https://github.com/twitter/hadoop-lzo
git clone https://github.com/twitter/hadoop-lzo
ps： 下载的时，有时候会连接超时，所以多试几次，就可以下载。
2.编译hadoop-lzo的源码
cd hadoop-lzo
mvn clean package
cd ~/twiter-hadoop-lzo/hadoop-lzo/target/
ls
3.上传hadoop-lzo-0.4.20-SNAPSHOT.jar 到hadoop各个节点的安装目录的/usr/local/hadoop/share/hadoop/common/目录下
hadoop-lzo.jar文件：
ls /usr/local/hadoop/share/hadoop/common/
4. 修改各个hadoop节点的hadoop的配置文件:
vi hadoop-env.sh :
添加如下配置：
# Extra Java CLASSPATH elements. Optional.
export HADOOP_CLASSPATH="<extra_entries>:$HADOOP_CLASSPATH:${HADOOP_HOME}/share/hadoop/common"
#export JAVA_LIBRARY_PATH=${JAVA_LIBRARY_PATH}:/usr/local/hadoop/lib/native:/opt/glibc-2.14/lib
export JAVA_LIBRARY_PATH=${JAVA_LIBRARY_PATH}:/usr/local/hadoop/lib/native
vi core-site.xml :
添加如下配置：
<property >
<name >io.compression.codec.lzo.class </name>
<value >com.hadoop.compression.lzo.LzoCodec </value>
</property >
<property >
<name >io.compression.codecs </name>
<value> org.apache.hadoop.io.compress.DefaultCodec,com.hadoop.compression.lzo.LzoCodec,org.apache.hadoop.io.compress.GzipCodec,org.apache.hadoop.io.compress.DefaultCodec,com.hadoop.compression.lzo.LzopCodec,org.apache.hadoop.io.compress.BZip2Codec </value>
</property >
vi mapred-site.xml
<property>
<name >mapred.compress.map.output </name>
<value >true </value>
</property>
<property>
<name >mapred.map.output.compression.codec </name>
<value >com.hadoop.compression.lzo.LzoCodec </value>
</property>
<property>
<name >mapreduce.map.env </name>
<value >LD_LIBRARY_PATH=/ usr/local/hadoop /lzo/lib</value>
</property >
<property >
<name >mapreduce.reduce.env </name>
<value >LD_LIBRARY_PATH=/ usr/local/hadoop /lzo/lib</value>
</property >
<property >
<name >mapred.child.env </name>
<value >LD_LIBRARY_PATH=/ usr/local/hadoop /lzo/lib</value>
</property >
5.分发 配置文件到所有的hadoop服务器节点
#分发hadoop-lzo.jar
./upgrade.sh distribute temp/allnodes_hosts /letv/setupHadoop/hadoop-2.6.0/share/hadoop/common/hadoop-lzo-0.4.20-SNAPSHOT.jar /usr/local/hadoop/share/hadoop/common/
#分发修改好的hadoop配置文件
./upgrade.sh distribute cluster_nodes hadoop-2.6.0/etc/hadoop/mapred-site.xml /usr/local/hadoop/etc/hadoop/
./upgrade.sh distribute cluster_nodes hadoop-2.6.0/etc/hadoop/core-site.xml /usr/local/hadoop/etc/hadoop/
./upgrade.sh distribute cluster_nodes hadoop-2.6.0/etc/hadoop/hadoop-env.sh /usr/local/hadoop/etc/hadoop/
