Question

How to check whether a file in HDFS location is exist or not, using Oozie?

In my HDFS location I will get a file like this test_08_01_2016.csv at 11PM

Answer 1

you can use EL expression in oozie like:

         
            
              ${fs:exists('/path/test_08_01_2016.csv')} 
            
            
         

You can also build the name of the file using simple shell script using capture output.
