             Summary: PySpark Streaming doesn't support Context recovery from checkpoint in HDFS
                 Key: SPARK-10091
                 URL: https://issues.apache.org/jira/browse/SPARK-10091
             Project: Spark
          Issue Type: Bug
          Components: PySpark, Streaming
    Affects Versions: 1.4.1, 1.4.0, 1.3.1, 1.3.0
            Reporter: Stanislav Los


Apparently, PySpark Streaming application can't recover from a checkpoint that was stored in HDFS. Method StreamingContext.getOrCreate looks for an existing checkpoint at local file system only. 

{code:title=pyspark.streaming.StreamingContext.getOrCreate()}
if not os.path.exists(checkpointPath) or not os.listdir(checkpointPath):
   ssc = setupFunc()
   ssc.checkpoint(checkpointPath)
   return ssc
{code}

In case if this is taken care of, next piece of code fails anyway (data is present in hdfs):

{code:title=pyspark.streaming.StreamingContext.getOrCreate()}
try:
   jssc = gw.jvm.JavaStreamingContext(checkpointPath)
except Exception:
   print >>sys.stderr, "failed to load StreamingContext from checkpoint"
{code}
            raise
