  1. Hadoop 101 Training class

    The instructor Ms. Desai was very fast with the material presentation and a lot of her words are muffled and hard to understand. The video did not stay on slide long enough for students to view it and the next one pops up. One of the worst online class I have taken

    • Replace Hadoop 101 video content

      Asma Desai has not done a good job in narrating the contents. I would suggest replacing the video for the benefit of audience

        • Create database/tables in Hive using ssh to systemt.datascientistworkbench.com

          Good Day,

          I ssh systemt.datascientistworkbench.com. Then I start hive using "hive" command. I try to create database/tables in hive but it says I don't have access.

          I see many test kind of hive databases which people have created. How can I create database/tables in hive?

          Please advise.

          Thanks.

          -Shakeel

          • Unable to retake final exam due to Network Issues

            Due to Network Issues , I was unable to write my final exam. Later when I clicked on Final exam, it says "You have submitted your timed exam. "

            So there should be some or the other way to overcome this issue.

                This is actually the default behavior of the current version of the Learning Management System we are using. This works much better in a later version that we are going to be migrating to.

                      • There should be a way to re-attempt the final test.

                        I have attempted for one test and was failed to score 60% mark. I have prepared for the exam again , but there is no option for second attempt.
                        You should provide option for re-attempt after 10 days or some limit.

                          Thank you all for your suggestions. We allow re-attempts for exam questions on legitimate case by case basis only. Rather than post your request here, kindly open a Support Ticket with your request. To do so, go into the course for which you want to re-attempt and click on the blue “Support” button in the middle right of the page and under “Contact Support” enter your request mentioning the course and a justification. Please be patient as it may take a few days to review your request.

                          • Should be able to retake learning modules and retake exams.

                            Should be able to retake modules and retake exams. I work on this from office and need to disconnect unexpectedly at time due to work.
                            I noticed that if I have to leave during a final exam then the exam automatically submits even if you have not finished the exam.. and I cannot retake..

                                It would be better to post/link the Course Completion Certificate and/or Badges to the Linkedin profile. I think it would also advertise the Cognitive Class at the same time giving the user more credentials in the data science Field

                                  Currently, it seems impossible to check progress or completion for a course from the completion page. This is tedious, especially for people with distributed time slots and lots of open courses.

                                  • Do not have any score for the final exam.

                                    I atttend the final exam, but haven't got any score.

                                    I selected the answers for all the questions, but nothing happened when I click "check", so I clicked to submit the test. It told me the score will be displayed on the progress page. But the score is still 0 on the progeress page.

                                        • Include an icon for "LinkedIn" on the Certificate page

                                          I was going through the Certificate page for the course "Predictive Modeling Fundamentals 1" and noticed that it would be good to include an icon for "LinkedIn" so that students can see their certificates on their Linkedin profiles.
