Duo Zhang commented on HBASE-21947:
-----------------------------------
Fixed the variable name warning. For the line length, there are lot of very
long lines and do not know what is the indent rule... And for other warnings it
is not easy to fix, methods too long and branch condition too complicate...
> TestShell is broken after we remove the jackson dependencies
