Spark Client Running Issues 2.7.2

Hi,

I have installed Spark 2.7.2 on a Ubuntu Machine, Earlier My version of 2.6.3 was working fine.Once I replaced old version with Spark 2.7.2 it stopped working, When i launch it, it keeps on loading and stops after 10-12 seconds.

I have separately installed Sun Java 8.0.60.

Spark is not even showing any errors in the Error Log.

Can someone having idea over this issue, please share your resolutions.

Thanks,

Sukh
