Hi, I have already installed cdh manager and access WEBUI well.Every function is OK,but have one configure issues. Here is some lines I copied. ``` Memory on host cloud1 is overcommitted. The total memory allocation is 63.9 GiB bytes but there are only 78.7 GiB bytes of RAM (15.7 GiB bytes of which are reserved for the system). Visit the Resources tab on the Host page for allocation details. Reconfigure the roles on the host to lower the overall memory allocation. Note: Java maximum heap sizes are multiplied by 1.3 to approximate JVM overhead. ``` And I try to lower the 'Memory Overcommit Validation Threshold' value .It does not work.How could I do? Please give me some advises.
