Examples with UnHealthyContainerStates org.hadoop.ozone.recon.schema.ContainerSchemaDefinition.UnHealthyContainerStates used on opensource projects

Example 1 with UnHealthyContainerStates

use of org.hadoop.ozone.recon.schema.ContainerSchemaDefinition.UnHealthyContainerStates in project ozone by apache.

the class ContainerEndpoint method getUnhealthyContainers.

/**
 * Return
 * {@link org.apache.hadoop.ozone.recon.api.types.UnhealthyContainerMetadata}
 * for all unhealthy containers.
 *
 * @param state Return only containers matching the given unhealthy state,
 *              eg UNDER_REPLICATED, MIS_REPLICATED, OVER_REPLICATED or
 *              MISSING. Passing null returns all containers.
 * @param limit The limit of unhealthy containers to return.
 * @param batchNum The batch number (like "page number") of results to return.
 *                 Passing 1, will return records 1 to limit. 2 will return
 *                 limit + 1 to 2 * limit, etc.
 * @return {@link Response}
