Example 3 with SdxWaitException

use of com.sequenceiq.datalake.service.sdx.flowwait.exception.SdxWaitException in project cloudbreak by hortonworks.

the class SdxWaitTaskService method waitFor.

/**
 * Will start a wait task on an SDX cluster.
 * For the frequency of checks and the total amount of time allowed for the task, please check {@linkplain PollingConfig} in the waitTask
 *
 * This wait service uses {@linkplain com.dyngr.Polling} as the underlying polling mechanism, meaning:
 * - if the polling succeeds, the method returns
 * - if there is a timeout, or the wait task wants to indicate a negative result, then an exception is thrown of type {@linkplain PollerException}
 * - optionally you can set to stop on any encountered exceptions, check {@linkplain PollingConfig.stopPollingIfExceptionOccured} for that
 *
 * @param sdxWaitTask A wait task with polling parameters as well as the algorithm for polling itself
 * @param <V> The type of parameter returned by the underlying poller package's AttemptMaker interface, hidden from outside world
 * @throws SdxWaitException is thrown if a {@linkplain PollerException} is reached
