By default processes not managed by Cloudera Manager will have no limit. | memory.limit_in_bytes | -1 MiB | rm_memory_hard_limit | true |
Cgroup Memory Soft Limit | Soft memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process if and only if the host is facing memory pressure. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 B to specify no limit. By default processes not managed by Cloudera Manager will have no limit. | memory.soft_limit_in_bytes | -1 MiB | rm_memory_soft_limit | true |
