----------------------------------------

             Summary: Support OpenSSL 1.1.0 LTS
                 Key: HADOOP-16647
                 URL: https://issues.apache.org/jira/browse/HADOOP-16647
             Project: Hadoop Common
          Issue Type: Task
            Reporter: Wei-Chiu Chuang


See Hadoop user mailing list 
http://mail-archives.apache.org/mod_mbox/hadoop-user/201910.mbox/%3CCADiq6%3DweDFxHTL_7eGwDNnxVCza39y2QYQTSggfLn7mXhMLOdg%40mail.gmail.com%3E

Hadoop 2 supports OpenSSL 1.0.2.
Hadoop 3 supports OpenSSL 1.1.0 (HADOOP-14597) and I believe 1.0.2 too.

Per OpenSSL blog https://www.openssl.org/policies/releasestrat.html
* 1.1.0 is EOL 2019/09/11
* 1.0.2 EOL 2019/12/31
* 1.1.1 is EOL 2023/09/11 (LTS)

Many Hadoop installation relies on the OpenSSL package provided by Linux 
distros, but it's not clear to me if Linux distros are going support 
1.1.0/1.0.2 beyond this date.

We should make sure Hadoop works with OpenSSL 1.1.1, as well as document the 
openssl version supported. File this jira to test/document/fix bugs.
