Vikas Vishwakarma commented on HBASE-20896:
-------------------------------------------

Apache build Hadoop QA tests have passed and reviewboard has been updated with 
the latest patch

locally I have run mvn test -P runDevTests to include server tests which also 
passed

Perf test results are given below and show 5-10% improvement (PE result tests 
tends to vary between iterations) :

|| test || 1.4.6 (ms) || HBASE-20896 (ms) || %diff || 
| scan all rows | 27669 | 26257 | 5 | 
| scan more CQ | 81308 | 76493 | 6 | 
| PE scan | 8917 | 8488 | 5 | 
| PE scan10 | 215134 | 209203 | 3 | 
| PE scan100 | 663645 | 650348 | 2 | 
| PE scanseq | 99696 | 94888 | 5 |

So this request is now ready for review. After that I can start working on the 
main branch changes.
