使用的hadoop是cdh4.2.1版本 spark1.1,需要配置hadoop-native和lzo native 在spark-env.sh加入 HADOOP_CONF_DIR=/etc/hadoop/conf?SPARK_SUBMIT_CLASSPATH=$SPARK_SUBMIT_CLASSPATH:/etc/hive/conf:/opt/cloudera/parcels/HADOOP_LZO/lib/hadoop/lib/hadoop

使用的hadoop是cdh4.2.1版本 spark1.1,需要配置hadoop-native和lzo native

在spark-env.sh加入

HADOOP_CONF_DIR=/etc/hadoop/conf
?
SPARK_SUBMIT_CLASSPATH=$SPARK_SUBMIT_CLASSPATH:/etc/hive/conf:/opt/cloudera/parcels/HADOOP_LZO/lib/hadoop/lib/hadoop-lzo.jar
#SPARK_SUBMIT_LIBRARY_PATH=$SPARK_SUBMIT_LIBRARY_PATH:/opt/cloudera/parcels/CDH/lib/hadoop/lib/native:/opt/cloudera/parcels/HADOOP_LZO/lib/hadoop/lib/native
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cloudera/parcels/CDH/lib/hadoop/lib/native:/opt/cloudera/parcels/HADOOP_LZO/lib/hadoop/lib/native

我加了SPARK_SUBMIT_LIBRARY_PATH发现是加入了java.library.path,但是丢了默认的配置。改为加入LD_LIBRARY_PATH里

spark-defaults.conf的配置

spark.ui.port   8810
spark.executor.extraLibraryPath /opt/cloudera/parcels/CDH/lib/hadoop/lib/native:/opt/cloudera/parcels/HADOOP_LZO/lib/hadoop/lib/native

可能还需要加上 spark.executor.extraClassPath,但我当前还是单机测试,没配也能跑成功。。
启动spark-sql试试,打开监控页面看看 http://xxxx:8810/environment/ 是否配置正确。
