> ||Heading 1||Heading 2||
> |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
