How do I fix GC overhead limit exceeded?
Solution
- Identify the objects in your application that occupy a large space on the heap.

What is GC overhead in spark?

How do I reduce the GC time on my Spark?
To avoid full GC in G1 GC, there are two commonly-used approaches: Decrease the InitiatingHeapOccupancyPercent option’s value (the default value is 45), to let G1 GC starts initial concurrent marking at an earlier time, so that we are more likely to avoid full GC.
How do I reduce the memory usage on my Spark?
In order, to reduce memory usage you might have to store spark RDDs in serialized form. Data serialization also determines a good network performance. You will be able to obtain good results in Spark performance by: Terminating those jobs that run long.

What is GC allocation failure?
A GC allocation failure means that the garbage collector could not move objects from young gen to old gen fast enough because it does not have enough memory in old gen. This can cause application slowness.
How do I make my Spark job faster?
Partitioning your DataSet While Spark chooses good reasonable defaults for your data, if your Spark job runs out of memory or runs slowly, bad partitioning could be at fault. If your dataset is large, you can try repartitioning (using the repartition method) to a larger number to allow more parallelism on your job.
