--------------------------------------
Hi, nope it's simple case class, exactly this:
{code}
case class ParsedUserAgent (
user_agent: String,
parser_version: String,
client_type: Option[String],
client_name: Option[String],
client_version: Option[String],
operating_system_name: Option[String],
operating_system_version: Option[String],
operating_system_platform: Option[String],
device_type: Option[String],
device_brand: Option[String],
device_model: Option[String],
is_bot: Option[Boolean],
is_mobile: Option[Boolean],
is_desktop: Option[Boolean]
)
{/code}
Flow itself is a bit more complicated as such structures are being read from
HDFS, filtered, projected, distinct-collected, inserted into datasets again,
unioned with other dataset, grouped and reduced.
In meantime there are some repartitions and caches using
StorageLevel.MEMORY_AND_DISK_SER
When it first happened i tried:
- removing intermediate dataset saves/caches
- removing explicit repartitions
- switching from kryo serialziation to standard java serialziation
But no of those solved a problem.
I also tried to create spark-shell equivalent flow (but on simple structures)
but it didn't trigger bug

> Reporter: Damian Momot
>
> Not really sure what's exact reproduction path. It's first job which was
