Subject [jira] [Commented] (HDFS-3508) avoid OOM while deserializing DelegationTokenIdentifer
Date Tue, 05 Jun 2012 21:09:23 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13289720#comment-13289720
] 

Daryn Sharp commented on HDFS-3508:
-----------------------------------

I see.  I agree it would be a good idea to move the max length into {{AbstractDelegationTokenIdentifier}}
so {{Text}} isn't "polluted" with another's object notion of the max length of its fields.

Naming it something other than what it's defined to be would be nice.  Ie. something like
{{AbstractDelegationTokenIdentifier.USER_MAX_LEN}} instead of {{ONE_MEGABYTE}}.  If we were
to decide that 4KB was more than generous, it'd be goofy to rename the constant to {{FOUR_KILOBYTES}}.
