> Running Hadoop Archive tool (HAR) against source/dest that are not HDFS does not work today.
> Example:
> {noformat}
> hadoop archive -archiveName foo.har -p ofs://ozone1/vol2/bucket2/src/ ofs://ozone1/vol2/bucket2/dst/
> {noformat}
> The command fails because it's essentially a MapReduce job and for some reason it does not obtain Ozone delegation token (only HDFS and KMS)
> The failure:
> {noformat}
> 22/11/30 18:12:10 INFO mapreduce.Job: Job job_1669745757520_0001 failed with state FAILED due to: Job setup failed : java.io.IOException: org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]
> at org.apache.hadoop.ipc.Client$Connection$1.run(Client.java:789)
> at java.security.AccessController.doPrivileged(Native Method)
> ...
> {noformat}
> The workaround is to add the ozone path as the default file system:
> {noformat}
> export HADOOP_OPTS="$HADOOP_OPTS -Dfs.defaultFS=ofs://ozone1/vol2/bucket2"
> {noformat}
> A proper fix should make sure HAR requests delegation tokens from src/dest file system too.
