> |NameNode new generation size|Default size of Java new generation for
> NameNode (Java option -XX:NewSize) Note: The value of NameNode new generation
> size (default size of Java new generation for NameNode (Java option
> -XX:NewSize)) should be 1/8 of maximum heap size (-Xmx). Ensure that the
> value of the namenode_opt_newsize property is 1/8 the value of maximum heap
> size (-Xmx).|
> However when we show the help tool tip for this setting we don't show this
> info at all. This info is very helpful to setup right values. Please show
> that recommendation is 1/8 of heap memory
