Josef Zahner updated NIFI-8423: ------------------------------- Attachment: nifi-app_log.png > Timezone wrong in UI for an 8 node cluster > ------------------------------------------ > > Key: NIFI-8423 > URL: https://issues.apache.org/jira/browse/NIFI-8423 > Project: Apache NiFi > Issue Type: Bug > Components: Core UI > Affects Versions: 1.13.2 > Environment: 8 Node NiFi Cluster on CentOS 7 > OpenJDK 1.8.0_282 > Local timezone: Europe/Zurich (CEST or UTC+2h) > Reporter: Josef Zahner > Priority: Critical > Labels: centos, cluster, openjdk, timezone > Attachments: image-2021-04-13-15-14-02-162.png, > image-2021-04-13-15-14-06-930.png, image-2021-04-13-15-14-56-690.png, > manual_configured_timezone_gui_output.png, nifi-app_log.png > > > We just upgraded to NiFi 1.13.2 and Java 1.8.0_282 > On our 8 node NiFi 1.13.2 cluster with timezone Europe/Zurich (CEST/CET), we > have the issue that the UI does display the correct timezone (CEST, so UTC > +2h), but in fact the time is displayed as UTC. NTP is enabled and working. > The OS configuration/location is everywhere the same (doesn't matter if > single or cluster NiFi). My tests below are all done at around 15:xx:xx local > time (CEST). > As you can see below, the timezone seems to be correct, but the time itself > within NiFi is 2h behind (so in fact UTC) compared to Windows. In earlier > NiFi/java versions it was enough to multiple times restart the cluster, but > on the newest versions this doesn't help anymore. It shows most of the time > CEST with the wrong time or directly UTC. > !image-2021-04-13-15-14-06-930.png! > > The single NiFi instances or the 2 node clusters are always fine. The issue > exists only on our 8 node cluster. > NiFi Single Node Screenshot, which is fine (CEST, so UTC + 2h): > !image-2021-04-13-15-14-02-162.png! > > If we set the -Duser.timezone to "Europe/Zurich" in bootstrap.conf, the UI > shows no summer time, so only GMT+1 instead of GMT+2. As well not what we > want. > {code:java} > java.arg.20=-Duser.timezone="Europe/Zurich"{code} > !image-2021-04-13-15-14-56-690.png! > > What Matt below suggested has been verified, all servers (single nodes as > well as clusters) are reporting the same time/timezone. > [https://community.cloudera.com/t5/Support-Questions/NiFi-clock-is-off-by-one-hour-daylight-savings-problem/td-p/192942] > > So the question remains, where on a NiFi cluster comes the time from the UI > and what could cause it that it is wrong? Sometimes I get UTC, sometimes I'm > getting CEST but the time is anyhow UTC instead of CEST... I really need to > have the correct time in the UI as I don't know what the impact could be on > our dataflows. > > Any help would be really appreciated. -- This message was sent by Atlassian Jira (v8.3.4#803005)
