    The two types of writes are:

    There are mainly two types of writes in HDFS: posted and non-posted write.

    1) Posted Write is when we write it and forget about it, without worrying about the acknowledgement. It is similar to our traditional Indian post.

    2) In a Non-posted Write, we wait for the acknowledgement. It is similar to the today’s courier services. Naturally, non-posted write is more expensive than the posted write. It is much more expensive, though both writes are asynchronous.
