Subject [jira] [Commented] (HDFS-7984) webhdfs:// needs to support provided delegation tokens
Date Fri, 23 Oct 2015 23:35:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14972112#comment-14972112

HeeSoo Kim commented on HDFS-7984:

Anthony is right. {noformat} HADOOP_TOKEN_FILE_LOCATION {noformat} supports to read delegation
token for WebHDFSFileSystem.
However, {noformat} HADOOP_TOKEN_FILE_LOCATION{noformat} is only support one file. ugi can
have multiple tokens in credential. This patch supports multiple delegation token files as
{noformat} -Dhadoop.token.files=filename1,filename2{noformat}

> 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.
