Tathagata Das updated SPARK-6752: --------------------------------- Fix Version/s: 1.4.0 > Allow StreamingContext to be recreated from checkpoint and existing > SparkContext > -------------------------------------------------------------------------------- > > Key: SPARK-6752 > URL: https://issues.apache.org/jira/browse/SPARK-6752 > Project: Spark > Issue Type: Improvement > Components: Streaming > Affects Versions: 1.1.1, 1.2.1, 1.3.1 > Reporter: Tathagata Das > Assignee: Tathagata Das > Priority: Critical > Fix For: 1.4.0 > > > Currently if you want to create a StreamingContext from checkpoint > information, the system will create a new SparkContext. This prevent > StreamingContext to be recreated from checkpoints in managed environments > where SparkContext is precreated. > Proposed solution: Introduce the following methods on StreamingContext > 1. {{new StreamingContext(checkpointDirectory, sparkContext)}} > - Recreate StreamingContext from checkpoint using the provided SparkContext > 2. {{new StreamingContext(checkpointDirectory, hadoopConf, sparkContext)}} > - Recreate StreamingContext from checkpoint using the provided SparkContext > and hadoop conf to read the checkpoint > 3. {{StreamingContext.getOrCreate(checkpointDirectory, sparkContext, > createFunction: SparkContext => StreamingContext)}} > - If checkpoint file exists, then recreate StreamingContext using the > provided SparkContext (that is, call 1.), else create StreamingContext using > the provided createFunction > Also, the corresponding Java and Python API has to be added as well. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
