We are developing a machine learning web application. When the user/users is/are trying to upload the huge dataset(from any source) it should be moved into HDFS. How can we achieve this? Can we run Nifi server on HDFS machine, to get this work done?Can we create separate pipelines for different sources like SQLdb/csv/etc and trigger them.Does it support multiple users trying to upload their dataset? I am new to BigData field, please provide me some suggestions. Please help me, in which forums can I post this question.
