The operation failed because the value "channelIsolation" is required for the configuration setting "parallelRegionConfig" in order to change the width of a parallel region. The value for the "parallelRegionConfig" setting is not set, defaults to default_parallelRegionConfig_value.
The Streams Application Manager cannot complete the operation to change the width of a parallel region because "channelIsolation" is required for the configuration setting "parallelRegionConfig".
In order to specify a new configuration value, resubmit the job using streamtool submitjob -C parallelRegionConfig=channelIsolation. If using a job configuration overlay file with submitjob, specify "channelIsolation" as the value for the "fusionType" attribute in the "ParallelRegionConfig" section.
