Kubernetes memory usage is spiking more than 15Gb, but local run on ubuntu takes much less. I figured out that Kubernetes does not use swaps. However, I could not find any specific parameter to control this spiking of memory in case a swap is not present.
Even At 2 threads, memory usage spikes to ~15GB.

You can use 'jmap -histo' to print out the number of objects per class, run it a few times to see which class of objects keep increasing.

All I could sense is an info (org.apache.hadoop.io.compress.CodecPool) INFO Got brand-new compressor [.gz] It looks like the object is being created without recycling and memory leaks is causing the system to shut down.
