While it's always recommended to have a good knowledge of Java programming because MR low level programming will become easy for you.
You can code MR in other programming languages such as Python, however, this will add an extra layer of interpreter which is not very helpful for performance.
On CCA175 certification front, your Java programming expertise is not evaluated. You are provided selection option for tool sets based on which you can answer the certification questions.
Hope this helps.

I am working as an Hadoop Administrator for the past 2.5 years, Basically i am a Teradata Administrator. one of our important client request for BigData solution for processing more than 100 Million CSV records, so i entered into Big data world (REALLY BIG WORLD) and I am still learning like student :)
Once we are entered into BIG data world we can't able to skip the Hadoop. so i am working for past 2.5 years in hadoop tools (Hue, Hive, HBase, PIG, Map-Reduce, Sqoop,kafka,Storm etc...).
Initially i am really struggled to survive in hadoop environment (New tools including JAVA) but now i am really happy to here (community) i am learning as well as waiting for the big future too.
I am very passionate to play cricket.

My name is Brant. I'm a researcher at Johns Hopkins. My background is in biomedical research with an emphasis on machine learning and natural language processing. I'm coming over from mostly large shared memory and MPI machines/clusters. I do have lots of Java programming experience but most of our applications aren't Java based. I've worked on Hadoop/Accumulo based applications before but am new to the dev ops/configuration/deployment aspects.
I'm currently trying to get my dockerized applications deployed in hadoop streaming on one of our clusters and eventually hoping to get longer running dockerized gpu applications running in slider. We're using docker because we can encapsulate our c++/python/etc depedencies with our programs.

Hello! I'm very new to the Hadoop / Cloudera environment and hoping to learn much from this community. My career arc has been software developer, software architect, and enterprise architect working entirely in the agribusiness industry. I just started a new job and have been given the task of identifying big data use cases to drive value from our Cloudera environment. So, here we go!
