ozone (docker) volume create: "WARN Unable to load native-hadoop library for your platform"

[pjotrek-b]

Running ozone commands inside a docker image, freshly pulled from DockerHub (according to docs).

When trying to create a volume, I get an error (actually an endless loop, retrying):

$ ozone sh volume create /vol1

2024-05-23 21:41:38 WARN NativeCodeLoader:60 - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
2024-05-23 21:41:41 INFO RetryInvocationHandler:422 - com.google.protobuf.ServiceException: java.net.ConnectException: Call From 20c05fb69b5f/172.17.0.2 to localhost:9862 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused, while invoking $Proxy21.submitRequest over nodeId=null,nodeAddress=localhost:9862 after 1 failover attempts. Trying to failover after sleeping for 4000ms. Current retry count: 1.

Any help or advice appreciated 😄

btw: I've read the Connection Refused article linked in the error message.

And indeed, running telnet localhost 9862 gives me a connection refused.

But why?
All I did was run/start the docker container with default settings.

All I did was run/start the docker container with default settings.

Can you please provide the command used?

Based on #6721 I guess this is the command:

docker run -d -p 9878:9878 -p 9876:9876 apache/ozone

The problem is that Ozone Manager exits due to misconfiguration. Filed HDDS-10909 for this bug. Thank you for reporting the problem.

In the meantime, please try using docker-compose (see "Running a pseudo-cluster with multiple containers" section in the same doc).

[pjotrek-b]

Yes, that command.
Thanks for drawing the connection between my 2 postings.

Sorry!
I forgot to link the tutorial documentation I was referring to, here too 😊

I also already used docker-compose (pseudo-cluster with 3 nodes, as in the docs) - and it started, but it was too late yesterday for me to try out connections. Will do that.
