I am Krishna. I have over 11 years of consulting experience in Business Intelligence and Analytics.
At present, I am co-founder, managing partner and consultant at Hitaay Consulting Pvt. Ltd., India.
Hitaay Consulting Pvt. Ltd. is a Business Intelligence and Analytics consulting and service enterprise which operates from India and Romania. We have started working in Big Data technology from 2015.
As a part of Cloudera Community, I look forward to contributing and honing towards Big Data and Cloudera technologies expertise.
I'm Prashant, having 4 years of experience in shell scripting, ETL tool, db2 database. I am working in big data from past 6 months on hive, impala, HUE.
I want to get certified in CCA Spark and Hadoop Developer Exam (CCA175).
I have a hadoop cluster installed in my office with cloudera(hive, impala, pig, sqoop, spark, oozie etc.)
Don't have knowledge/experience on Java/MR, really confused how to start preparing for this certification.
Can someone please give me some direction.
One of the best way to prepare for CCA175 certification is undergoing 4 days - Cloudera Developer training offered by Cloudera and its traning partners.
This is a very comprehensive training program and probably prerequisite for taking up CCA175 certification.
In addtion to this training, you require either at least 1 month of hands on training (depending upon your CDH expertise) or atleast one end-to-end Big Data implemeation experience.
Your prepration should be more focused towards HDFS, Spark, Sqoop, Impala and Hive.
And lastly, this 120 mins Cloudera certification are more focused towards hands on experience than theory.
Therefore, more your practice, better your changes are for clearing this certification.
Hope this is helpful for you.
Good luck for your prepration and certification test.
I have one more query. Since i am from Data warehousing background with very less knowledge of Java, so i am finding it difficult to write map-reduce jobs in java.
Do they check java programming for MR jobs in this exam ?
For spark - Can you please suggest any online MOOC training/book to start it ?
Cloudera Developer training are out of budget for me.
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.
