[ovirt-devel] master and 4.1 dwhd Fails to Start (was ovirt_experimental_master Fails: PostgreSQL is not Accessible During Engine Setup)

[Anton Marchukov]

Hello All.

We checked this with did and postgres connection error is not an error
(although it prints stacktrace... cannot we not print stacktraces, please,
for antyhing that we handle in code... it is really confusing when you need
to find the root cause).

The test is checking for dwhd to be up using systemd:

    testlib.assert_true_within_short(
        lambda: engine.service('ovirt-engine-dwhd').alive()
    )

that runs:

/usr/bin/systemctl status --lines=0 ovirt-engine-dwhd
lago.ssh: DEBUG: Command 90e98548 on lago-basic-suite-master-engine
returned with 3
lago.ssh: DEBUG: Command 90e98548 on lago-basic-suite-master-engine output:
 ● ovirt-engine-dwhd.service - oVirt Engine Data Warehouse
   Loaded: loaded (/usr/lib/systemd/system/ovirt-engine-dwhd.service;
enabled; vendor preset: disabled)
   Active: activating (auto-restart) (Result: exit-code) since Tue

 Main PID: 22448 (code=exited, status=1/FAILURE)
   CGroup: /system.slice/ovirt-engine-dwhd.service

dwhd log [1] has the following error:

Error: Could not find or load main class
ovirt_engine_dwh.historyetl_4_2.HistoryETL

so this looks to be the actual problem. The latest job failed with this is
[2]. This also affects 4.1, e.g. [3].
