Subject [jira] [Commented] (HADOOP-12563) Updated utility to create/modify token files
Date Tue, 10 May 2016 01:18:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15277434#comment-15277434
] 

Hitesh Shah commented on HADOOP-12563:
--------------------------------------

[~aw] Did you take a look at the stack trace in question?

{code}
Caused by: java.io.IOException: Unknown version 1 in token storage.
        at org.apache.hadoop.security.Credentials.readTokenStorageStream(Credentials.java:*215*)
        at org.apache.hadoop.security.Credentials.readTokenStorageFile(Credentials.java:*194*)
{code}

Could you clarify what you mean by "Tez should not be reading the file outside of the provided
hadoop classes" ?

> hdfs fetchdt is missing some critical features and is geared almost exclusively towards
HDFS operations.  Additionally, the token files that are created use Java serializations which
are hard/impossible to deal with in other languages. It should be replaced with a better utility
in common that can read/write protobuf-based token files, has enough flexibility to be used
with other services, and offers key functionality such as append and rename. The old version
file format should still be supported for backward compatibility, but will be effectively
deprecated.
> A follow-on JIRA will deprecrate fetchdt.
