-------------------------------
Summary: Should add diagnostics in DAGAppMaster when recovery
error happens
Key: TEZ-2261
URL: https://issues.apache.org/jira/browse/TEZ-2261
Project: Apache Tez
Issue Type: Bug
Reporter: Jeff Zhang
Should add diagnostics in DAGAppMaster when recovery error happens, otherwise
AM is shutdown and the next dag submission will just throw
SessionNotRunningException which would confuse users.
{code}
if (this.historyEventHandler.hasRecoveryFailed()) {
LOG.warn("Recovery had a fatal error, shutting down session after" +
" DAG completion");
sessionStopped.set(true);
}
{code}
