+# SeaTunnel Runs On Spark
+
+Spark is a powerful high-performance distributed calculate processing engine. More information about it you can search for `Apache Spark`
+
+### Set Spark Configuration Information In The Job
+
+Example:
+I set some spark conf for this job
+
+```
+env {
+  spark.app.name = "example"
+  spark.sql.catalogImplementation = "hive"
+  spark.executor.memory= "2g"
+  spark.executor.instances = "2"
+  spark.yarn.priority = "100'
+  hive.exec.dynamic.partition.mode = "nonstrict"
+  spark.dynamicAllocation.enabled="false"
+}
+```
+
+### Command Line Example
+
+#### Spark on Yarn Cluster
+
+```
+./bin/start-seatunnel-spark-3-connector-v2.sh --master yarn --deploy-mode cluster --config config/example.conf
+```
+
+#### Spark on Yarn Cluster
+
+```
+./bin/start-seatunnel-spark-3-connector-v2.sh --master yarn --deploy-mode client --config config/example.conf
+```
+
+### How To Set Up A Simple Spark Job
+
+This is a simple job that runs on Spark. Randomly generated data is printed to the console
+
+```
+env {
+  # common parameter
+  parallelism = 1
+
+  # spark special parameter
+  spark.app.name = "example"
+  spark.sql.catalogImplementation = "hive"
+  spark.executor.memory= "2g"
+  spark.executor.instances = "1"
+  spark.yarn.priority = "100"
+  hive.exec.dynamic.partition.mode = "nonstrict"
+  spark.dynamicAllocation.enabled="false"
+}
+
+source {
+  FakeSource {
+  schema = {
+    fields {
+      c_map = "map<string, array<int>>"
+      c_array = "array<int>"
+      c_string = string
+      c_boolean = boolean
+      c_tinyint = tinyint
+      c_smallint = smallint
+      c_int = int
+      c_bigint = bigint
+      c_float = float
+      c_double = double
+      c_decimal = "decimal(30, 8)"
+      c_null = "null"
+      c_bytes = bytes
+      c_date = date
+      c_timestamp = timestamp
+      c_row = {
+        c_map = "map<string, map<string, string>>"
+        c_array = "array<int>"
+        c_string = string
+        c_boolean = boolean
+        c_tinyint = tinyint
+        c_smallint = smallint
+        c_int = int
+        c_bigint = bigint
+        c_float = float
+        c_double = double
+        c_decimal = "decimal(30, 8)"
+        c_null = "null"
+        c_bytes = bytes
+        c_date = date
+        c_timestamp = timestamp
+      }
+    }
+  }
+}
+}
+
+transform {
+  # If you would like to get more information about how to configure seatunnel and see full list of transform plugins,
+  # please go to https://seatunnel.apache.org/docs/transform-v2/sql
+}
+
+sink{
+   Console{}   
+}

+
+### How To Run A Job In A Project
+
+After you pull the code to the local, go to the `seatunnel-examples/seatunnel-spark-connector-v2-example` module and find `org.apache.seatunnel.example.spark.v2.SeaTunnelApiExample` to complete the operation of the job.
