--------------------------------------------------------------
The reason is that default value of "classloader.parent-first-patterns.default"
contains "org.apache.hadoop.", and parent class loader includes hadoop, so
ChildFirstClassLoader will not load Configuration from plugin jar. Actually if
job runs on yarn cluster with no bundled hadoop, there may be also conflict
between hadoop-s3 and yarn. My colleagues and I make some discussions about the
solutions
# remove "org.apache.hadoop." from parent-first-patterns globally, but it can
change other component's behavior, and need to be cautious.
# provide a plugin-level option for parent-first-patterns, and each plugin can
decide what dependency to inherit from parent class loader.
# make hadoop dependency in Flink pluggable, including hdfs and yarn, so that
parent class loader will not contain hadoop. As mentioned in FLINK-11952, it's
a general approach in the long term.
At the moment, solution 2 may be the better choice. What do you think? [~arvid
