Task Example

Simple:

This example reads from a Hudi COW table and configures Kerberos for the environment, printing to the console.

# Defining the runtime environment
env {
  # You can set flink configuration here
  execution.parallelism = 2
  job.mode = "BATCH"
}
source{
  Hudi {
    table.path = "hdfs://nameserivce/data/hudi/hudi_table/"
    table.type = "cow"
    conf.files = "/home/test/hdfs-site.xml;/home/test/core-site.xml;/home/test/yarn-site.xml"
    use.kerberos = true
    kerberos.principal = "test_user@xxx"
    kerberos.principal.file = "/home/test/test_user.keytab"
  }
}
