Subject [jira] [Commented] (HDFS-7984) webhdfs:// needs to support provided delegation tokens
Date Tue, 01 Dec 2015 06:42:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15033190#comment-15033190

HeeSoo Kim commented on HDFS-7984:

If you run the command on user account2, you should use HADOOP_CLIENT_OPTS parameter.
on user account2:
HADOOP_CLIENT_OPTS="${HADOOP_CLIENT_OPTS} -Dhadoop.token.files=/tmp/token" hadoop fs -ls /user/account1

When you use the {{-Dproperty=value}} pattern, the property should be mention before the java
hadoop fs -Dhadoop.token.files=/tmp/token -ls /user/account1
If you use the above command, the property of {{sun.java.command}} has the {{-Dhadoop.token.files}}
property as a value.
sun.java.command=org.apache.hadoop.fs.FsShell  -Dhadoop.token.files=/tmp/token -ls /user/account1

> When using the webhdfs:// filesystem (especially from distcp), we need the ability to
inject a delegation token rather than webhdfs initialize its own.  This would allow for cross-authentication-zone
file system accesses.
