| <h2><a name="Timeouts"></a>Timeouts</h2> |
| <p>The timeout used by the ADL SDK can be overridden with the hadoop property <code>adl.http.timeout</code>. Some timeouts in compute frameworks may need to be addressed by lowering the timeout used by the SDK. A lower timeout at the storage layer may allow more retries to be attempted and actually increase the likelihood of success before hitting the framework’s timeout, as attempts that may ultimately fail will fail faster.</p></section><section> |
| <h2><a name="SSL_Socket_Channel_Mode"></a>SSL Socket Channel Mode</h2> |
| <p>ADL SDK will by default attempt to create secure socket connections over OpenSSL as they provide significant performance improvements over Https. If there are runtime issues, SDK will default connections over Default_JSE. This can be overridden with the hadoop property <code>adl.ssl.channel.mode</code>. Possible values for this config are OpenSSL, Default_JSE and Default (default). Setting the config to OpenSSL or Default_JSE will try the connection to only that mode.</p></section> |
