----------------------------------
Summary: Federation: Yarn running app web can't be unable to
connect, because AppMaster can't redirect to the right address.
Key: YARN-10775
URL: https://issues.apache.org/jira/browse/YARN-10775
Project: Hadoop YARN
Issue Type: Bug
Reporter: zhengchenyu
I setup a yarn federation cluster, I can't connect the running app web, but the
completed app's web works.
By some debug info, I found the reason. Because AmIpFilter.PROXY_HOSTS is set
by configuration (do it in
AmFilterInitializer.getProxyHostsAndPortsForAmFilter). In client configuration,
there are no configuation about 'rm web port', so the url can't not be
redirect.
I think client should not know rm's web port, especially in yarn federation
mode.
Note:
Here is my specially configuration for client. I use ha for select router
randomly.
|| config || value ||
| yarn.resourcemanager.ha.enabled | true |
| yarn.resourcemanager.ha.rm-ids | r1 |
|yarn.resourcemanager.address.r1 | router_host:8050 |
|yarn.resourcemanager.scheduler.address.r1 | localhost:8049 |
