I have small data in Hbase table crawled via Nutch. It us using Apache Gora as an ORM. I have found a lot of example (mapreduce) to process data in single table in Hbase. But my problem is that I have to copy data into multiple tables (in reducer). Without Gora, there exists some guide e.g., this question etc. But how to do it for my case.
Apache Gora Reducer for multi-table output with Hbase

I never did what you ask, but you might glimpse the answer in the Gora Tutorial "Constructing the job" section. There, there is an example of reducer configuration that says:
Then, instead of using
GoraReducer.initReducerJob()
you can just configure your own reducer, as told following your link (if it is a correct answer):Know that in the example before, the mapper emits
(TextLong, LongWritable)
key-values, so your reducer would be something like, from the link you wrote and the answer:Again, I never did this... so maybe doesn't work :\
