streamtool unrestrictdomainhost

Usage

unrestrictdomainhost [-d,--domain-id <did>] --tags <tag>,... [-U,--User <user>] [-h,--help] [--trace <level>] [-v,--verbose <level>] [--zkconnect {<host>:<port>},... | --embeddedzk] <hostname> ... | <hostname>,...

The streamtool unrestrictdomainhost command removes the restriction that was placed on a static resource for specific application purposes.

Authority

To run this command, you must have write authority on the config domain object and write authority on the host domain object.

Description

This command removes tag restrictions on hosts. This removal instructs the scheduler not to restrict PE placements. As a result, PEs that do not reference the specific tags in their host pool definitions are still allowed to run on the hosts.

Options

-d,--domain-id <did>
Specifies the domain identifier.

If you do not specify this option, Streams uses the domain name that is set in the STREAMS_DOMAIN_ID environment variable. By default, that domain name is StreamsDomain. If you are using the interactive streamtool interface, it uses the name of the active domain for the current streamtool session or else it prompts you for the domain name.

The active domain for the current streamtool session is set every time that you successfully run a streamtool command with a -d or --domain-id option. Alternatively, you can run the streamtool domain command in the interactive interface.

--embeddedzk

Specifies to use the embedded copy of ZooKeeper. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify either this option or the --zkconnect option, Streams uses the ZooKeeper connection that is associated with the active domain or the domain that is specified in the --domain-id option. Streams determines which connection maps to the domain by using cached information about the domains. In this scenario, if the domain identifier is not unique in the Streams configuration cache, the command fails.

-h,--help
Specifies to show the command syntax.
--tags <tag>
Specifies a list of tags.
--trace <level>
Specifies the trace setting. The following valid levels are listed in order of increasing verbosity, which is to say that the first level in the list generates the least amount of information:
  • off
  • error
  • warn
  • info
  • debug
  • trace
The default value is off.
-U,--User <user>
Specifies an Streams user ID that has authority to run the command.
-v,--verbose <level>
Specifies to provide more detailed command output. The verbosity level can be 0-3, where 0 disables detailed reporting and each increment provides more detailed output.
--zkconnect <{<host>:<port>},...>

The name of one or more host and port pairs that specify the configured ZooKeeper servers. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify this option, Streams tries to use:

  1. The --embeddedzk option
  2. The value from the STREAMS_ZKCONNECT environment variable
  3. A ZooKeeper connection string that is derived from cached information about the current domain.

Arguments

hostname
Specifies the host name or IP address for a host in the domain.
