I gave certification yesterday night.I couldn’t clear the certification.The certification is in old format only
Things to be noted:-
1.The cluster is very damn slow. The text is getting displayed in VM after 10 seconds after you typed here.
2.Time management is the key. I failed because I’m unable to manage time accordingly.Wasted 30 mins on sqoop questions.
3. Don’t try to touch all the questions. Make sure first atleast 7 questions are answered. Target for 7 answers to be correct.
They have a 25 million records in table. I wrote the command accordingly
sqoop import --connect “connection string” --username cloudera --password cloudera --table table-name --target-dir “/x/y/z” --as-texfile
When i connected to db using sqoop and ran eval queries it worked fine. But when i ran the import jobs it failed because of connection error. Im unable to answer import and export questions because of this .Not sure what exactly went wrong
I’m unable to figure out what exactly went wrong in above command.
