[jira] [Commented] (TOREE-443) Make delayed kernel execution
timeout configurable
[ https://issues.apache.org/jira/browse/TOREE-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16259544#comment-16259544 ]

--------------------------------------
GitHub user sanjay-saxena opened a pull request:
https://github.com/apache/incubator-toree/pull/147
Support for --spark-context-initialization-timeout command-line option
This change addresses TOREE-443. Instead of hardcoding the
timeout to 100ms, --spark-context-initialization-timeout
command-line option has been introduced to make it configurable.
On slow/busy nodes, an appropriate timeout can be specified
to avoid the confusing messages in the notebook UI. Added
unit tests to CommandLineOptionsSpec.scala.

> In the *kernel* sub-project's {{org.apache.toree.kernel.api.Kernel.scala}}, when we do the spark context delayed initialization, there is hardcoded wait of 100 ms. This usually works ok, but in slow machines or busy nodes it's not enough and cause confusion to users as it's going to try to initialize the context and display the message on the notebook ui twice.
> We should enable users to configure the timeout via an environment variable.
