Hi, all:
I use function updateStateByKey in Spark Streaming, I need to store the states
for one minite, I set "spark.cleaner.ttl" to 120, the duration is 2 seconds,
but it throws Exception
Caused by:
org.apache.hadoop.ipc.RemoteException(java.io.FileNotFoundException): File does
not exist: spark/ck/hdfsaudit/receivedData/0/log-1430139541443-1430139601443

Why?
my code is
ssc = StreamingContext(sc,2)
kvs = KafkaUtils.createStream(ssc, zkQuorum, group, {topic: 1})
kvs.window(60,2).map(lambda x: analyzeMessage(x[1]))\
.filter(lambda x: x[1] != None).updateStateByKey(updateStateFunc) \
.filter(lambda x: x[1]['isExisted'] != 1) \
.foreachRDD(lambda rdd: rdd.foreachPartition(insertIntoDb))
