Liyin Tang updated SPARK-14105:
-------------------------------
Affects Version/s: 1.5.2
Component/s: Streaming
Spark Core
> Serialization issue for KafkaRDD
> --------------------------------
>
> Key: SPARK-14105
> URL: https://issues.apache.org/jira/browse/SPARK-14105
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, Streaming
> Affects Versions: 1.5.2
> Reporter: Liyin Tang
>
> When using DISK or Memory to persistent KafkaDirectInputStream, it will
> serialize the FetchResponse into blocks. The FetchResponse contains the
> ByteBufferMessageSet where each Kafka Message is just one slice of the
> underlying ByteBuffer.
> When serializing the KafkaRDDIterator, it seems like the entire underlying
> ByteBuffer in ByteBufferMessageSet will be serialized for each and every
> message. This will cause block size easily exceeds 2G, and lead to
> "java.lang.OutOfMemoryError: Requested array size exceeds VM limit" or
> "FileChannelImpl.map -> exceeds Integer.MAX_VALUE:"
> The consumer fetch is the default value (1M). I tried to reduce fetch size,
> but it will cause other errors like errRanOutBeforeEnd.
> Here are exceptions I got for both Memory and Disk persistent.
