Subject Spark Streaming : Could not compute split, block not found
Date Fri, 01 Aug 2014 17:55:24 GMT
We are using Sparks 1.0 for Spark Streaming on Spark Standalone cluster and
seeing the following error.

	Job aborted due to stage failure: Task 3475.0:15 failed 4 times, most
recent failure: Exception failure in TID 216394 on host java.lang.Exception: Could not compute
split, block input-0-1406869340000 not found

We are using the Memory_DISK serialization option for the input streams. And
the stream is also being persisted since we have multiple transformations
happening on the input stream.

    val lines = KafkaUtils.createStream[String, Array[Byte], StringDecoder,
DefaultDecoder](ssc, kafkaParams, topicpMap,


We are aggregating data every 15 minutes as well as an hour. The
spark.streaming.blockInterval=10000 so we minimize the blocks of data read.

The problem started at the 15 minute interval but now I'm seeing it happen
every hour since last night.

Any suggestions?
