Subject [jira] [Commented] (HADOOP-12752) Improve diagnostics/use of envvar/sysprop credential propagation
Date Fri, 29 Jan 2016 20:51:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15124188#comment-15124188

Allen Wittenauer commented on HADOOP-12752:
-------------------------------------------

We should really discourage HADOOP_TOKEN_FILE_LOCATION.  Also, hadoop.token.files is only
in trunk.

> * document the system property {{hadoop.token.files}}. 
> * document the env var {{HADOOP_TOKEN_FILE_LOCATION}}.
> * When UGI inits tokens off that or the env var , log this fact
> * when trying to load a file referenced in the env var (a) trim it and (b) check for
it existing, failing with a message referring to the ENV var as well as the file.
