def
getOrCreate(checkpointPath: String, creatingFunc: Function0[JavaStreamingContext], hadoopConf: Configuration, createOnError: Boolean): JavaStreamingContext
Either recreate a StreamingContext from checkpoint data or create a new StreamingContext.
Either recreate a StreamingContext from checkpoint data or create a new StreamingContext. If checkpoint data exists in the provided
checkpointPath
, then StreamingContext will be recreated from the checkpoint data. If the data does not exist, then the provided factory will be used to create a JavaStreamingContext.- checkpointPath
Checkpoint directory used in an earlier StreamingContext program
- creatingFunc
Function to create a new JavaStreamingContext
- hadoopConf
Hadoop configuration if necessary for reading from any HDFS compatible file system
- createOnError
Whether to create a new JavaStreamingContext if there is an error in reading checkpoint data.
