This CDH cluster has been install for months, and be used to backup logs.
Today I try to run flink on yarn, and want to open yarn web ui to check flink taskmanagers' state, i find 8088 port connect refuse.
This site can’t be reached 47.74.***.*** refused to connect. Search Google for *** *** 8088 ERR_CONNECTION_REFUSED
yarn port & address config as follows:
yarn.resourcemanager.address 8032 yarn.resourcemanager.scheduler.address 8030 yarn.resourcemanager.resource-tracker.address 8031 yarn.resourcemanager.admin.address 8033 yarn.resourcemanager.webapp.address 8088 yarn.resourcemanager.webapp.https.address 8090
Even curl 'http://ip:8088' on the resource manager host, also get "connection refuse"
[root@bigdata-cdh02 ~]# netstat -tunlp|grep 8088 tcp 0 0 172.21.0.20:8088 0.0.0.0:* LISTEN 20606/java
BTW, I check yarn logs, it seems that yarn has successfully allocated resources for flink.
