sohurdc updated SPARK-52564:
----------------------------
Description:
Once checkpointing is enabled in Spark Streaming, configuration changes require
deleting the checkpoint, which results in loss of state.
{{// Function to create and setup a new StreamingContext
def functionToCreateContext(): StreamingContext = \{
val ssc = new StreamingContext(...) // new context
val lines = ssc.socketTextStream(...) // create DStreams
...
ssc.checkpoint(checkpointDirectory) // set checkpoint directory
ssc
}
// Get StreamingContext from checkpoint data or create a new one
val context = StreamingContext.getOrCreate(checkpointDirectory,
functionToCreateContext _)
// Do additional setup on context that needs to be done,
// irrespective of whether it is being started or restarted
context. ...
// Start the context
context.start()
context.awaitTermination()}}
