Spark Applicaion (Stages) UI does not recognize line number
I'm running my spark application on a standalone server mode.
When trying to check performance on the Spark stages UI (spark-server:4040) I can see all stages but line number in the description field is always -1
Stage ID: 0
Description: count at null:-1
Stage ID: 3
Description: repartitions at null: -1
I tried both with jdk1.6.0_37 & jdk1.7.0_45
Do you know how I can see the line number in the UI/Logs?
