Hi there, How to automate sqoop incremental import using sqoop job? As for as I know, sqoop job remembers the last value. If we create a sqoop job like sqoop job --create myjob -- import --connect blah blah.. sqoop exec myjob and automate the job, It will create the job each time it executes. So, we will get job already exists error. So, Is it possible to automate sqoop incremental import using sqoop job? Please let me know your knowledge on this. Thanks in advance.

Hi there, I have an idea about Multi-threading in general but not sure how it is used in Hadoop. Based on my knowledge, Yarn is responsible for managing/controlling Spark/Mapreduce job resources, can't think of Multi-threading here. Not sure whether it can be used anywhere else in Hadoop Eco System. I would appreciate if anybody could provide some information on this. Many thanks,

I tried the implicit function in the way as you suggested and it works very well. Thank you for explaining why the implicit functions are kept in Companion Object classes. You have done very good job... One more request is that, Could you please send me any shell script if you have to automate sqoop incremental import job? Once again Thank you very much...!!!

Dear jfrazee, Thank you very much for your prompt reply. Somehow i figured out the answer in different way by defining the implicit function within the object where the main function is , but outside the main function. But, I'll try your approach too.. Once again Thank you very much. I appreciate your support..

Hi, I'm new to Scala and learning now. I'm trying a program with implicit conversions. But, it shows error in the main program. I've attached the program file for your reference. Please note that both the Rational class and Rational main object in the same project. So, i don't have to import the Rational class to the main program. I'm trying these programs in Scala eclipse IDE. Please let me know your information on this.. Thanks in advance. Regards, Jeeva implicit-error.txt
