Validated
Storm configs are specified as a plain old map. This class provides constants for all the configurations possible on a Storm cluster.
Each constant is paired with an annotation that defines the validity criterion of the corresponding field. Default values for these
configs can be found in defaults.yaml.

the manually set cpu share for each CGroup on supervisor node. -
STORM_CGROUP_CGEXEC_CMD

STORM_CGROUP_MEMORY_LIMIT_TOLERANCE_MARGIN_MB
Please use STORM_SUPERVISOR_MEMORY_LIMIT_TOLERANCE_MARGIN_MB instead. The amount of memory a worker can exceed its allocation before cgroup will kill it. -
STORM_CGROUP_INHERIT_CPUSET_CONFIGS
To determine whether or not to cgroups should inherit cpuset.cpus and cpuset.mems config values form parent cgroup Note that cpuset.cpus and cpuset.mems configs in a cgroup must be initialized (i.e. contain a valid value) prior to being able to launch processes in that cgroup. The common use case for this config is when the linux distribution that is used does not support the cgroup.clone_children config. -
STORM_CGROUP_MEMORY_ENFORCEMENT_ENABLE
Java does not always play nicely with cgroups. It is coming but not fully implemented and not for the way storm uses cgroups. In the short term you can disable the hard memory enforcement by cgroups and let the supervisor handle shooting workers going over their limit in a kinder way. -
STORM_SUPERVISOR_MEMORY_LIMIT_TOLERANCE_MARGIN_MB
Memory given to each worker for free (because java and storm have some overhead). This is memory on the box that the workers can use. This should not be included in SUPERVISOR_MEMORY_CAPACITY_MB, as nimbus does not use this memory for scheduling. -
STORM_SUPERVISOR_HARD_MEMORY_LIMIT_MULTIPLIER
A multiplier for the memory limit of a worker that will have the supervisor shoot it immediately. 1.0 means shoot the worker as soon as it goes over. 2.0 means shoot the worker if its usage is double what was requested. This value is combined with STORM_SUPERVISOR_HARD_MEMORY_LIMIT_OVERAGE and which ever is greater is used for enforcement. This allows small workers to not be shot. -
STORM_SUPERVISOR_HARD_LIMIT_MEMORY_OVERAGE_MB
If the memory usage of a worker goes over its limit by this value is it shot immediately. This value is combined with STORM_SUPERVISOR_HARD_LIMIT_MEMORY_MULTIPLIER and which ever is greater is used for enforcement. This allows small workers to not be shot. -
STORM_SUPERVISOR_LOW_MEMORY_THRESHOLD_MB
If the amount of memory that is free in the system (either on the box or in the supervisor's cgroup) is below this number (in MB) consider the system to be in low memory mode and start shooting workers if they are over their limit. -
STORM_SUPERVISOR_MEDIUM_MEMORY_THRESHOLD_MB
If the amount of memory that is free in the system (either on the box or in the supervisor's cgroup) is below this number (in MB) consider the system to be a little low on memory and start shooting workers if they are over their limit for a given grace period STORM_SUPERVISOR_MEDIUM_MEMORY_GRACE_PERIOD_MS. -
STORM_SUPERVISOR_MEDIUM_MEMORY_GRACE_PERIOD_MS
The number of milliseconds that a worker is allowed to be over their limit when there is a medium amount of memory free in the system. -
STORM_WORKER_MIN_CPU_PCORE_PERCENT
The config indicates the minimum percentage of cpu for a core that a worker will use. Assuming the a core value to be 100, a value of 10 indicates 10% of the core. The P in PCORE represents the term "physical". A default value will be set for this config if user does not override. Workers in containers or cgroups may require a minimum amount of CPU in order to launch within the supervisor timeout. This setting allows configuring this to occur. -
STORM_WORKER_TOKEN_LIFE_TIME_HOURS
The number of hours a worker token is valid for. This also sets how frequently worker tokens will be renewed. -
STORM_OCI_NSCD_DIR
The directory of nscd - name service cache daemon, e.g. "/var/run/nscd/". nscd must be running so that profiling can work properly. -

STORM_OCI_READWRITE_BINDMOUNTS
A list of read-write bind mounted directories. -
STORM_OCI_CGROUP_PARENT
The cgroup root for oci container. (Also a --cgroup-parent config for docker command) Must follow the constraints of the docker command. The path will be made as absolute path if it's a relative path because we saw some weird bugs (the cgroup memory directory disappears after a while) when a relative path is used. Note that we only support cgroupfs cgroup driver because of some issues with systemd; restricting to `cgroupfs` also makes cgroup paths simple. -
STORM_OCI_IMAGE
Default oci image to use if the topology doesn't specify which oci image to use. -
STORM_OCI_ALLOWED_IMAGES
A list of oci image that are allowed. A special entry of asterisk(*) means any image is allowed, but the image has to pass other checks. Storm currently assumes OCI container is not supported on the cluster if this is not configured. -
STORM_OCI_SECCOMP_PROFILE
Specify the seccomp Json file to be used as a seccomp filter. -
STORM_OCI_IMAGE_HDFS_TOPLEVEL_DIR
The HDFS location under which the oci image manifests, layers, and configs directories exist. -
