sqoop is not working correctly and seems due to missing env. variable as below: any insight? [cloudera@quickstart Documents]$ sqoop import --connect jdbc:mysql:// 192.168.112.128/widget --username root --pcloudera --table myhadoop --as-textfile --target-dir /home/cloudera/Documents Warning: /usr/lib/sqoop/../accumulo does not exist!

Thanks for providing details related to training for certification Training is meant for Developers,Administrators and Data Analysyts So, question is: 1. What is the equvalent of CCA175 ( Developers) for Data analysts? it seems CCP(DE575) is the only certification track for data analysts 2. I am more interested in CCA175 certification, do I need to brush-up/learn python before i take training or appear for certification? it seems working knowledge of python is neccessary to qualify CCA175? 3. Is cloudera training neccessary or advisable if someone is new to Hadoop before appearing for ceritification exam? Just to give my back ground , I am in Database enginering,data modeling,data architecture for the last more than 15 years and mainly in Unix/linux/AIX environment. No JAVA experience.
