You may check if it makes sense to write a coprocessor doing an upsert for you, if it does not exist already. Maybe phoenix for Hbase supports this already.
Another alternative, if the records do not have an unique Id, is to put them into a text index engine, such as Solr or Elasticsearch, which does in this case a fast matching with relevancy scores. You can use also Spark and Pig there. However, I am not sure if Spark is suitable for these one row lookups. Same holds for Pig.

Write a batch process which will read from a file 2. Lookup hbase to see if the record exists. If so then need to compare incoming values with hbase and update fields which do not match. Else create a new record. My questions: 1. Is this a good use case for pig or spark? 2. Is there any way to read hbase for each incoming record in pig without writing map reduce code? 3. In case of spark I think we have to connect to hbase for every record. Is thr any other way? 4. What is the best connector for hbase which gives this functionality? Best Ayan
