----------------------------------
Summary: Not able to deploy Flink 1.3-SNAPSHOT on Openshit Paas
Key: FLINK-5847
URL: https://issues.apache.org/jira/browse/FLINK-5847
Project: Flink
Issue Type: Bug
Components: JobManager, Local Runtime
Affects Versions: 1.3.0
Environment: Openshift Paas
Reporter: xinyang gao
Priority: Blocker
Fix For: 1.3.0
I am now trying to deploy Flink-1.3-Snapshot on Openshift which is a
docker-environment. I was able to successfully deploy Flink-1.1.2 version on
Openshift although I encountered the exception that
"org.apache.flink.runtime.util.EnvironmentInformation - Error while
accessing user/group information via Hadoop utils.java.io.IOException: failure
to login", this exception was handled and finally the jobmanager can be fired
up on Openshift.
However when it comes 1.3-SNAPSHOT, it will finally incur the error that
"Exception in thread "main" java.lang.Exception: unable to establish the
security context" which is caused by "Caused by:
javax.security.auth.login.LoginException: java.lang.NullPointerException:
invalid null input: name", then the Jobmanager failed to start. The reason
looks like is that containers run on openshift are assigned a random uid rather
than running as the default uid declared by the image. this can cause problems
for some images. So for the container it does not have a current user name,
however due to some reason in Flink 1.3-SNAPSHOT Hadoop needs to extract the
user name from UNIX, if null it will throw an exception and stop firing up.
