Re: Hdfs to hbase template
Posted by Mike Thomsen <mi...@gmail.com>.
I think the general flow would be...
ListHDFS -> FetchHDFS -> UpdateAttribute to attach a schema.name attribute
-> PutHBaseRecord
Not sure what an "upsert delete operation" is in this context. HBase
doesn't support upsert operations because an update is essentially the same
thing as a Put.
