Abstract: Embodiments of the present disclosure provide solutions for determining an elected search head captain is unqualified for the position, identifying a more qualified search head, and transferring the captain position to the more qualified search head. A method is provided that includes referencing qualification parameters in an elected search head captain, determining whether the newly elected search head captain is qualified for the position based on the parameters, identifying a more qualified search head to be the search head captain if the newly elected search head captain is determined to be unqualified for the position, and transferring the position of captain to the more qualified search head. The qualification parameters may include, for example, a pre-determined static flag set by an administrator of the search environment, and configuration replication status that corresponds to the most recent configuration state of the search head as recorded by the previous search head captain.

Abstract: Embodiments of the present disclosure provide techniques for efficiently and accurately performing propagation of search-head specific configuration customizations across multiple individual configuration files of search heads of a cluster for a consistent user experience. The cluster of search heads may be synchronized such that the search heads operate to receive the configuration or knowledge object customizations from one or more clients from a central or lead search head. To reduce the amount of data that is transferred during propagation, the list of configuration or knowledge object customizations maintained in each search head is filtered from the list of the lead search head until a divergence point is determined. Once determined and communicated to the lead search head, the lead search head sends the configuration and knowledge object customization data that is absent from the internal list of the member search head.
