How to encrypt AK and SK using Livy restAPI to submit sparkJob

[Huizhe Wang]

Hi,

I am using Livy RestApI to submit spark job.  I used s3a to replace HDFS. I
have to write fs.s3a.access.key and fs.s3a.sercet.key directly in
core-site.xml, as there is no these conf param in Livy API.
How could I encrypt my AK and SK?

Yours.
