Thanks Hitesh. I had another reply in this thread, the main reason is I enabled HDFS HA, Tez cannot find hdfs-site.xml, so there is UnknownHostException in the AM log.
The application works after I uploaded hdfs-site.xml to the Tez-lib-Uris. But it looks strange Tez cannot find hdfs-site. Ps. All fine if I disable Tez.
