  • hadoop2.6 上hive运行 报“native-lzo library not available”异常处理

    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。

    EN0044b849

    ####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

    Image

    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：

    EN0044b858 EN0044b868EN0044b877

    ls /usr/local/hadoop/share/hadoop/common/

    Image(1)

    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

    Image(2)

    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/
