Chen Liang commented on HDFS-14058:
-----------------------------------
Another test done:
6. Performed manual failover while a TeraSort job was running. Specifically, I
had two NNs ha1 and ha2, one as ANN and one as ONN. After started a TeraSort
job with 1800+ mappers and 500 reducers, I changed ONN to SNN, and then call
{{hdfs haadmin -failover --forcefence ha1 ha2}}, and also reconfigured the VIP
to the other name node. Although some task attempts ended up failed due to
timeout, the job finished successfully.
