[jira] [Comment Edited] (TEZ-1712) SSL context gets destroyed too
soon after downloading data from one of the vertices
[ https://issues.apache.org/jira/browse/TEZ-1712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14186464#comment-14186464 ]

What impact does not shutting down the ssl connection have in terms of container re-use. Is there a possibility that we'll end up trying to use ssl for subsequent DAGs which may not be configured to use it ?
>>
Good catch. In setupConnection(), check needs to be added to use of SSL connection only when "httpConnParams.sslShuffle == true". This would ensure that http and https are honored in container-reuse scenario appropriately. Attached patch addresses this.

> In scenarios where a vertex has to download shuffle data from multiple sources, sslContext gets destroyed soon after data is downloaded from one of the vertex. This causes SSL handshake exception when data needs to be downloaded from other vertices and fetchers to fail.
