“Could not find or load main class” when running with systemctl
Hello,
I am trying to run hbase 1.3.1 with systemctl on fedora 26 but without
success.
If I execute `/usr/lib/hbase/bin/start-hbase.sh` it starts just fine.
But I need to write systemctl wrapper around hbase.
I don't understand what am I doing wrong. I am using hdfs user to start
hbase in both cases.
Here is my /etc/systemd/system/hbase.service :
[Unit]
Description=Hbase Service
[Service]
User=hdfs
Group=hadoop
Type=forking
ExecStart=/usr/lib/hbase/bin/start-hbase.sh
ExecStop=/usr/lib/hbase/bin/stop-hbase.sh
TimeoutStartSec=2min
Restart=on-failure
[Install]
WantedBy=multi-user.target
After `systemctl start hbase` execution `systemctl status hbase` shows:
Error: Could not find or load main class Cannot
What am I doing wrong?
Sincerely

I'd think journalctl would have more logs on systemd stuff, no? Can you try
running that against your service (journalctl -u, if memory serves me).
My guess from the capitalized "Cannot" is that it's running some command
which is failing and then trying to pass that failing arg's output in to
the start script.

Re: “Could not find or load main class” when running with systemctl
Posted by Stack <st...@duboce.net>.
HBase has its own set of logs. Are you unable to find any? Or have
systemctl direct stdout/stderr somewhere that persists past startup.
