Justin Uang created HADOOP-16050: ------------------------------------ Summary: Support setting cipher suites for s3a file system Key: HADOOP-16050 URL: https://issues.apache.org/jira/browse/HADOOP-16050 Project: Hadoop Common Issue Type: Bug Affects Versions: 2.9.1 Reporter: Justin Uang Attachments: Screen Shot 2019-01-17 at 2.57.06 PM.png
We have found that when running the S3AFileSystem, it picks GCM as the ssl cipher suite. Unfortunately this is well known to be slow on java 8: [https://stackoverflow.com/questions/25992131/slow-aes-gcm-encryption-and-decryption-with-java-8u20.] In practice we have seen that it can take well over 50% of our CPU time in spark workflows. We should add an option to set the list of cipher suites we would like to use. !Screen Shot 2019-01-17 at 2.57.06 PM.png! -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
