-----------------------------------
Summary: Kerberos ticket renewal issue due static thread pool in
Iceberg library
Key: NIFI-13722
URL: https://issues.apache.org/jira/browse/NIFI-13722
Project: Apache NiFi
Issue Type: Bug
Reporter: Mark Bathori
Assignee: Mark Bathori
There is a static worker Thread Pool in Iceberg which is used in multiple parts
of the library:
https://github.com/apache/iceberg/blob/main/core/src/main/java/org/apache/iceberg/util/ThreadPools.java#L45
When the PutIceberg processor is started for the first time then this Thread
Pool will be initialized with the initial Kerberos user and the processor will
work properly until it is not restarted. When restart happens then a new
Kerberos user will be initialized but the Thread Pool will still reference to
the original Kerberos user so when the Kerberos ticket expires for the first
user then it won't be able to renew it.
Same issue happens when multiple processors are using the same classloader and
the processor which initialized the Thread Pool is stopped then the other
processors will start to fail.
