当我尝试向mesos群集提交spark应用程序时，出现以下异常：

/home/knoldus/application/spark-2.2.0-rc4/conf/spark-env.sh: line 40: export: `/usr/local/lib/libmesos.so': not a valid identifier

我已经建立了Spark使用

./build/mvn -Pmesos -DskipTests clean package

我在spark-env.sh中设置了以下属性：

export MESOS_NATIVE_JAVA_LIBRARY= /usr/local/lib/libmesos.so
export SPARK_EXECUTOR_URI= hdfs://spark-2.2.0-bin-hadoop2.7.tgz

在spark-defaults.conf中：

spark.executor.uri  hdfs://spark-2.2.0-bin-hadoop2.7.tgz
