class
JavaSparkContext extends Closeable
A Java-friendly version of org.apache.spark.SparkContext that returns org.apache.spark.api.java.JavaRDDs and works with Java collections instead of Scala ones.

- Note
Only one
SparkContext
should be active per JVM. You muststop()
the activeSparkContext
before creating a new one.

class
JavaSparkStatusTracker extends AnyRef
Low-level status reporting APIs for monitoring job and stage progress.
Low-level status reporting APIs for monitoring job and stage progress.
These APIs intentionally provide very weak consistency semantics; consumers of these APIs should be prepared to handle empty / missing information. For example, a job's stage ids may be known but the status API may not have any information about the details of those stages, so
getStageInfo
could potentially returnnull
for a valid stage id.To limit memory usage, these APIs only provide information on recent jobs / stages. These APIs will provide information for the last
spark.ui.retainedStages
stages andspark.ui.retainedJobs
jobs.- Note
This class's constructor should be considered private and may be subject to change.
