Kihwal Lee updated HDFS-10939: ------------------------------ Resolution: Fixed Hadoop Flags: Reviewed Fix Version/s: 2.8.0 Status: Resolved (was: Patch Available) Committed to branch-2 and branch-2.8 as well. > Reduce performance penalty of encryption zones > ---------------------------------------------- > > Key: HDFS-10939 > URL: https://issues.apache.org/jira/browse/HDFS-10939 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs > Affects Versions: 2.7 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Fix For: 2.8.0, 3.0.0-alpha2 > > Attachments: HDFS-10939.1.patch, HDFS-10939.2.patch, > HDFS-10939.branch-2.patch, HDFS-10939.patch > > > The encryption zone APIs should be optimized to extensively use IIPs to > eliminate path resolutions. The performance penalties incurred by common > operations like creation of file statuses may be reduced by more extensive > short-circuiting of EZ lookups when no EZs exist. All file creates should > not be subjected to the multi-stage locking performance penalty required only > for EDEK generation. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
