Subject [jira] [Commented] (HDFS-9724) WebHDFS listing is too slow after HDFS-6565
Date Wed, 03 Feb 2016 19:20:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15130942#comment-15130942

Haohui Mai commented on HDFS-9724:

bq. AFAIK, we don't have a re-entrant call pattern in WebHDFS though, and we just need to
worry about thread-safety. Am I missing something?

Thanks Chris for bringing this up. I just checked the code and confirmed your statement. I
think this change is safe.

It might be beneficial to add a comment to document the assumption.
