Example 52 with YarnRuntimeException

use of org.apache.hadoop.yarn.exceptions.YarnRuntimeException in project hadoop by apache.

the class TestNodeStatusUpdater method testNoRegistrationWhenNMServicesFail.

/**
   * Verifies that if for some reason NM fails to start ContainerManager RPC
   * server, RM is oblivious to NM's presence. The behaviour is like this
   * because otherwise, NM will report to RM even if all its servers are not
   * started properly, RM will think that the NM is alive and will retire the NM
   * only after NM_EXPIRY interval. See MAPREDUCE-2749.
