zhengchenyu updated YARN-10775:
-------------------------------
Description:
I setup a yarn federation cluster, I can't connect the running app web, but the
completed and accepted app's web works.
was:
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|
> Federation: Yarn running app web can't be unable to connect, because
> AppMaster can't redirect to the right address.
