环境如下：
vi /hadoop/spark/conf/spark-env.sh
export SPARK_CLASSPATH="/hadoop/spark/lib/mysql-connector-java.jar:/hadoop/spark/lib/sequoiadb-driver-1.12.jar:/hadoop/spark/lib/spark-sequoiadb_2.10-1.12.0.jar"
复制代码
在创建外部临时表时报错如下：
scala> sqlContext.sql("CREATE temporary table foobar USING com.sequoiadb.spark OPTIONS ( host 'master:11810,node1:11810,node2:11810', collectionspace 'foo', collection 'bar')")
16/06/14 18:22:52 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
