OssOps

class OssOps extends Logging with Serializable

Various utility classes for working with Aliyun OSS.

OSS URI:

There are two kinds of OSS URI:
Complete OSS URI: oss://accessKeyId:[email protected]/path
Simplified OSS URI: oss://bucket/path

like:
   oss://kj7aY*******UYx6:AiNMAlxz*************1PxaPaL8t
   @aBucket.oss-cn-hangzhou-internal.aliyuncs.com/fileA
   oss://aBucket/fileA

In simplified way, you need to config accessKeyId/accessKeySecret/endpoint
in SparkConf, like:
   SparkConf conf = new SparkConf()
   conf.set("spark.hadoop.fs.oss.accessKeyId", "kj7aY*******UYx6")
   conf.set("spark.hadoop.fs.oss.accessKeySecret",
   "AiNMAlxz*************1PxaPaL8t")
   conf.set("spark.hadoop.fs.oss.endpoint",
   "http://oss-cn-hangzhou-internal.aliyuncs.com")
