Hi community!    I am attempting to import multiple .csv files to HBase using importtsv. So far I have only read about people importing single files. Is this even possible, can I just run the import on the files individually and then import the HFiles? I'd appreciate any tips on how I go about that.    Thank you!  ebau ... View more

Hi! Sorry for digging out this thread, but I am currently facing the same problem and decided to run MR job to transform my data before importing it.   However, I am unsure what the data output should look like for it to be understood by HBase. As far as I know, HBase saves everything as bytes anyway, but makes a difference for timestamps. So,say I want to queue Factory_ID:YYYMMDD:Order_ID:UID for my composite key. Should I output them with ":" as a separator. Or just one after another? Will HBase be able to use this information to shard the table into different regions?   Thanks in advance! ... View more
