Allen Wittenauer commented on HDFS-12916:
-----------------------------------------
bq. I have included Hadoop tools lib folder, so which will be adequate to get
all its dependencies.
I think you've missed my point: not all of bits in tools are just Hadoop
clients. They have other dependencies that are outside of both tools and the
runtime jar.
bq. I have just ran distcp for sample, need to run other commands to know more
if they cause issue.
distcp and a few others are literallly YARN clients. Try enabling something
bigger like Azure or AWS.
bq. if I override all home variables(like hdfs_home, mapred_home) to same
client location in hadoop-layout.sh, it will have only shaded client jars.
We haven't even talked about things that people run with 'hadoop jar'.
At this point, I'm changing this to a new feature and moving it to HADOOP since
it isn't HDFS-specific. It's not a bug. Everything is working as intended.
