Yes. I am using batch variant. I will try your variant 02.03.2017 7:53 AM "Jingcheng Du" <dujin...@gmail.com> napisał(a):
What APIs are you using to execute the coprocessor? HTable#batchCoprocessorService? It executes the coprocessors regions by regions in each region server. How about using coprocessorService? This API should run coprocessors in parallel for different regions. 2017-03-02 14:32 GMT+08:00 Daniel Połaczański <dpolaczan...@gmail.com>: > I invoke my business logic which is similar to map reduce paradigm. > Everything works.
