  1. Hi Avkash,

    I hope my mail finds you well and in good health.
    I’m asking if you could assist me solve a problem I’m currently facing in using Hadoop as this is the first time to use it.
    I’m using Hadoop on my Ubuntu machine. And I’m trying to write a seq file using the below code, but the code finishes and says “sucessfully (or) read 202000 ….” and on the destintation folder I can’t find my output seq file.

    So I’d be very thankful if you could please advise why this is happening.

    Many Thanks Avkash for your kind assistance and support,

    Hussein
