             Summary: Hadoop Archive tool (HAR) should acquire delegation tokens from source and destination file systems
                 Key: HADOOP-18548
                 URL: https://issues.apache.org/jira/browse/HADOOP-18548
             Project: Hadoop Common
          Issue Type: Bug
          Components: tools
            Reporter: Wei-Chiu Chuang


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.
