Andrew Or created SPARK-12565:
---------------------------------
Summary: Document standalone mode jar distribution more clearly
Key: SPARK-12565
URL: https://issues.apache.org/jira/browse/SPARK-12565
Project: Spark
Issue Type: Improvement
Components: Documentation
Affects Versions: 1.0.0
Reporter: Andrew Or
There's a lot of confusion on the mailing list about how jars are distributed.
The existing docs are partially responsible for this:
{quote}
If your application is launched through Spark submit, then the application jar
is automatically distributed to all worker nodes.
{quote}
This makes it seem like even in cluster mode, the jars are uploaded from the
client (machine running Spark submit) to the cluster, which is not true.
We should clarify the documentation.
