-------------------------------------
Hmm, interesting. And security is OFF as you mentioned?
Can you try if it works if you completely remove the Hadoop uber jar from the
lib folder, and instead export the hadoop classpath as in
https://ci.apache.org/projects/flink/flink-docs-master/ops/deployment/hadoop.html
There was one fix to the Kerberos functionality between 1.4.0 and 1.4.2, which
is
https://github.com/apache/flink/commit/20146652baff31c3824f7ae31506b8c481cdf56c
The puzzling thing is that this particular commit does not modify the Hadoop
Uber Jar.
[~tzulitai] Do you have any thoughts why that could happen?

> Affects Versions: 1.4.1, 1.4.2
> Environment: * Flink-1.4.2 (Flink-1.4.1)
> * Hadoop 2.6.0-cdh5.13.0 with 4 nodes in service and {{Security is off.}}

> * Java 8
> *Description*
> I have a Java job in flink-1.4.0 which writes to HDFS in a specific path.

> *Description*
> I have a Java job in flink-1.4.0 which writes to HDFS in a specific path.
> After updating to flink-1.4.2 I'm getting the following error from Hadoop

> WARN org.apache.hadoop.security.UserGroupInformation:

> cause:org.apache.hadoop.security.AccessControlException: Permission denied:

> {code}
> *NOTE*:
> * If I run the same job on flink-1.4.0, Error disappears regardless of what
> version of flink (1.4.0 or 1.4.2) dependencies I have for job
> * Also if I run the job main method from my IDE and pass the same
> parameters, I don't get above error.
> *NOTE*:
> It seems the problem somehow is in
> {{flink-1.4.2/lib/flink-shaded-hadoop2-uber-1.4.2.jar}}. If I replace that
> with {{flink-1.4.0/lib/flink-shaded-hadoop2-uber-1.4.0.jar}}, restart the
> cluster and run my job (flink topology) then the error doesn't appear.
