Memory allocation issue in a Datanode .

Expert Contributor

Hello All ,


default value

Memory on host is overcommitted. The total memory allocation is 9.5 GiB bytes but there are only 7.6 GiB bytes of RAM (1.5 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.
