-------------------------------------
Summary: Option to disable GCM for SSL connections when running on
Java 8
Key: HADOOP-16371
URL: https://issues.apache.org/jira/browse/HADOOP-16371
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Sahil Takiar
Assignee: Sahil Takiar
This was the original objective of HADOOP-16050. HADOOP-16050 was changed to
mimic HADOOP-15669 and added (or attempted to add) support for Wildfly-OpenSSL
in S3A.
Due to the number of issues have seen with S3A + WildFly OpenSSL (see
HADOOP-16346), HADOOP-16050 was reverted.
As shown in the description of HADOOP-16050, and the analysis done in
HADOOP-15669, GCM has major performance issues when running on Java 8. Removing
it from the list of available ciphers can drastically improve performance,
perhaps not as much as using OpenSSL, but still a considerable amount.
