How do I create those variables? The help documentation says they are in JSP EL, but I'm unsure how to write in that. How would I make one that returns true if it's the 1st of the month, for example?

I got the following responses from Cloudera Certification. Regarding Question #1, the FAQ page has the most the up-to-date information. So right now I'd better hold off purchasing the exam until the DE575 is relaunched. Regarding Question #2, the course is the "Spark and Hadoop Developer" training course is the one I should take for preparing DE575. Regarding Question #3, the environment for the exam is fixed and only available on CDH. Candidates do not have the option to take the exam in an HDP environment. The skills tested are applicable to HDP development as well, it is in the developer track, so it should have nothing to do with the environment that it is running in. It is primarily interested in transforming data that sits on the cluster.

Thanks for sharing @JTT. As for entering code, you do have the option to add a code sample in the post editor.
This will open a pop-up to enter the code.
The final result looks like this ( I anonymized the IP addresses):
WARN [NiFi Web Server-363] o.a.nifi.web.server.HostHeaderHandler Request host header [example.com] different from web hostname [xxx.x.x.x(:xxxx)]. Overriding to [xxx.x.x.x:xxxx/nifi-api/flow/current-user]
While you cannot use this to format words in a sentence, it is helpful for large samples. I hope it helps.

@nishank_paras Let's assume your input FlowFile content looks like this: Date, IP, Description
01-30-2020, 10.0.0.1, server1
01-30-2020, 10.0.1.2, server2
01-30-2020, 10.0.3.4, server3
01-30-2020, 10.0.4.6, server4
01-30-2020, 10.0.10.2, server5 You would configure your ReplaceText processor as follows: The Search Value contains a java regular expression which will match on your entire line and uses one capture group. The Replacement Value says to replace everything matched by the Search Value Regex with only the value from capture group 1. We then configure ReplaceText to evaluate that Regex against each line. The resulting FlowFile output to the success relationship will have content that looks like this: IP
10.0.0.1
10.0.1.2
10.0.3.4
10.0.4.6
10.0.10.2 Hope this helps, Matt

The nifi database client is different from the one used to develop the application. The specific problem was in a field of a source table of the view where this field was used both to record numerical values and text and on this field the to_number oracle function was used to convert the text to numeric. But since the configuration is different from the docker, the format of numbers was ',.' so the data could not be transformed. The data in the productive database were somewhat different from those in the development database. I used a function where i use TO_NUMBER(REPLACE(NVL(TRIM(p_cadena),'0'),'.',',')); to solved this problem. (Only for docker)

@P_ As this is an older post you would have a better chance of receiving a resolution by starting a new thread. This will also provide the opportunity to provide details specific to your environment that could aid others in providing a more accurate answer to your question.

Hi @piosobc , The CDH pricing is under the 'Enterprise Data Hub' column on this page: https://www.cloudera.com/products/pricing.html So yes, it's the same as CDP. But as @cjervis mentioned in an earlier post it is best to discuss this with someone in our sales organization via Contact Us page on Cloudera.com. I think Cloudera Express will work > 100 nodes for CDH / CM 6.0 as this limit was introduced at 6.1. However, I don't recommend this as an approach as you would surely benefit from the enterprise-class features for more than 100 nodes. Also, as I mentioned in my earlier post, Cloudera is moving away from shipping Cloudera Express editions. Your best option is to consider a support version of CDH / CDP. Regards, Steve
