Daryn Sharp commented on HDFS-13951: ------------------------------------ Please don't combine unrelated patches on another Jira. Glad someone is fixing this. I forgot hacking this long ago. Also, there should be no need to conditionalize on hdfs. Just let the tokens stringify themselves. > HDFS DelegationTokenFetcher can't print non-HDFS tokens in a tokenfile > ---------------------------------------------------------------------- > > Key: HDFS-13951 > URL: https://issues.apache.org/jira/browse/HDFS-13951 > Project: Hadoop HDFS > Issue Type: Bug > Components: tools > Affects Versions: 3.2.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Minor > > the fetchdt command can fetch tokens for filesystems other than hdfs (s3a, > abfs, etc), but it can't print them, as it assumes all tokens in the file are > subclasses of > {{org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenIdentifier}} > & uses this fact in its decoding. It deserializes the token byte array > without checking kind and so ends up with invalid data. > Fix: ask the tokens to decode themselves; only call toStableString() if an > HDFS token. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
