KS3 Filesystem

In this page, we explain how to get your Hudi spark job to store into KS3.

KS3 configs​

There are two configurations required for Hudi-KS3 compatibility:

  • Adding KS3 Credentials for Hudi
  • Adding required Jars to classpath

KS3 Credentials​

Simplest way to use Hudi with KS3, is to configure your SparkSession or SparkContext with KS3 credentials. Hudi will automatically pick this up and talk to KS3.

Alternatively, add the required configs in your core-site.xml from where Hudi can fetch them. Replace the fs.defaultFS with your KS3 bucket name and Hudi should be able to read/write from the bucket.

  <property>
      <name>fs.defaultFS</name>
      <value>hdfs://ks3node</value>
  </property>

  <property>
      <name>fs.ks3.impl</name>
      <value>com.ksyun.kmr.hadoop.fs.Ks3FileSystem</value>
  </property>

  <property>
      <name>fs.ks3.AccessKey</name>
      <value>KS3_KEY</value>
  </property>

  <property>
