Subject [jira] [Commented] (YARN-2722) Disable SSLv3 (POODLEbleed vulnerability) in YARN shuffle
Date Thu, 23 Oct 2014 16:54:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14181560#comment-14181560

Stephen Chu commented on YARN-2722:
-----------------------------------

Hi [~ywskycn], thanks for making this change. Java 6 doesn't support TLSv1.2. Robert noted
this in HADOOP-11217 as well. Should we be adding TLSv1.2 in this patch?

> We should disable SSLv3 in HttpFS to protect against the POODLEbleed vulnerability.
> See [CVE-2014-3566 |http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566]
> We have {{context = SSLContext.getInstance("TLS");}} in SSLFactory, but when I checked,
I could still connect with SSLv3.
