Jean-Daniel Cryans commented on KUDU-1934: ------------------------------------------ Ok I thought I had gone back enough but I hadn't, so I finally found that log line. Maybe this is fine then. It just feels weird that the tserver would still try to do it every second after 2 weeks. Arguably this is an edge case, but that's how you then trigger bugs like KUDU-1933. > tservers aggressively try to reconnect to masters > ------------------------------------------------- > > Key: KUDU-1934 > URL: https://issues.apache.org/jira/browse/KUDU-1934 > Project: Kudu > Issue Type: Bug > Components: tserver > Affects Versions: 1.3.0 > Reporter: Jean-Daniel Cryans > Labels: newbie > > Related to KUDU-1933, I had mismatched 1.3 snapshots between the master and > the tservers which caused them to try to reconnect to the master infinitely. > Since they do it as fast as they can, the logs were quickly full of: > {noformat} > I0307 23:55:21.228502 70832 heartbeater.cc:291] Connected to a master server > at ve0120.halxg.cloudera.com:7051 > I0307 23:55:21.228528 70832 heartbeater.cc:359] Registering TS with master... > I0307 23:55:21.228865 70832 heartbeater.cc:389] Master > ve0120.halxg.cloudera.com:7051 requested a full tablet report, sending... > W0307 23:55:21.346961 70832 heartbeater.cc:499] Failed to heartbeat to > ve0120.halxg.cloudera.com:7051: Remote error: Failed to send heartbeat to > master: Not authorized: invalid CSR: CSR did not contain expected username. > (CSR: '' RPC: 'kudu') > I0307 23:55:22.347733 70832 heartbeater.cc:291] Connected to a master server > at ve0120.halxg.cloudera.com:7051 > I0307 23:55:22.347757 70832 heartbeater.cc:359] Registering TS with master... > I0307 23:55:22.348042 70832 heartbeater.cc:389] Master > ve0120.halxg.cloudera.com:7051 requested a full tablet report, sending... > W0307 23:55:22.467021 70832 heartbeater.cc:499] Failed to heartbeat to > ve0120.halxg.cloudera.com:7051: Remote error: Failed to send heartbeat to > master: Not authorized: invalid CSR: CSR did not contain expected username. > (CSR: '' RPC: 'kudu') > {noformat} > Sounds like we should do backoff retries. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
