In many java versions, SSLContext#getSocketFactory always returns a > new instance which completely breaks the cache. Clients flooding a service > with lingering per-request connections that can lead to port exhaustion. The > hadoop SSLFactory should cache the socket factory associated with the context. -- 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
