Affects Versions: 3.1.1
Reporter: ShuangQi Xia
Attachments: image-2022-07-29-18-06-20-950.png
we found that ,router print logs that indicate Observer NameNode state
changed to active always,here's the log
2022-03-18 11:00:54,589 | INFO | NamenodeHeartbeatService hacluster 11342-0 |
NN registration state has changed:
test101:25019->hacluster:11342:test103:25000-ACTIVE ->
test102:25019->hacluster:11342::test103:25000-OBSERVER |
MembershipStoreImpl.java:170
for code ,I fount that , when router request failed for some reson ,like
sockettimeout Excetion , failover to Observer NameNode,will update it's state
to Active
if (failover) {
// Success on alternate server, update
InetSocketAddress address = client.getAddress();
namenodeResolver.updateActiveNamenode(nsId, address);
}
