Hi,
Does this memory allocation referres to the physical memory allocated to the node? What's the best way to go about resolving this error?
Thanks
cluster: Configuration Issues
hadoop5.vm: Memory Overcommit Validation Threshold
Memory on host hadoop5.vm is overcommitted. The total memory allocation is 10.5 GiB bytes but there are only 11.5 GiB bytes of RAM (11.5 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.
