Daryn Sharp updated HDFS-12143: ------------------------------- Status: Patch Available (was: Open) > Improve performance of getting and removing inode features > ---------------------------------------------------------- > > Key: HDFS-12143 > URL: https://issues.apache.org/jira/browse/HDFS-12143 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Affects Versions: 2.8.0 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Attachments: HDFS-12143.patch > > > Getting a feature uses an iterator which is less performant than an indexed > for loop. Feature lookups are becoming more prolific so cycles count. > Removing a feature requires building a string for up to 3 precondition > checks. The worst case of 3 is the penalty for a successful removal. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
