Hi all,
I'm trying to work out a problem when using Spark Streaming, currently I
have the following piece of code inside a foreachRDD call:
Dataframe results = ... //some dataframe created from the incoming rdd -
moderately big, I don't want this to be shuffled
DataFrame t = sqlContext.table("a_temp_cached_table"); //a very small table
- that might mutate over time
DataFrame x = results.join(*broadcast(t)*, JOIN_COLUMNS_SEQ)
.groupBy("column1").count()
.write()
.mode(SaveMode.Append)
.save("/some-path/");
The intention of the code above is to distribute the "t" dataframe if
required, but avoid shuffling the "results".
This works fine when ran on scala-shell / spark-submit, but when ran from
within my executors I get the exception below...
Any thoughts? If I remove the *broadcast(t)* then it works fine but where my
big table is shuffled around.
