----------------------------------
Summary: 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
Affects Versions: 2.7
Reporter: Daryn Sharp
Assignee: Daryn Sharp
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.
