[SPARK-2157] Enable tight firewall rules for Spark #1777
Conversation
Uses spark.fileserver.port
Uses spark.broadcast.port
spark.replClassServer.port
spark.blockManager.port
Fails when running master+worker+executor+shell on the same machine. I think the issue is that both the shell and the executor attempt to start a ConnectionManager, which causes port conflicts. Solution is to attempt and increment on BindExceptions
- spark.fileserver.port - spark.broadcast.port - spark.replClassServer.port - spark.blockManager.port
We were passing the Master/Worker UI names as base paths for Jetty to use, which is obviously wrong in hindsight.
The existing documentation uses {master/worker}.ui.port, which doesn't actually work because SparkConf doesn't pick up system properties that are not prefixed by spark (SPARK-2857). We should at least document a working alternative.
QA tests have started for PR 1777. This patch merges cleanly. |

There is probably a better name for this. I just don't know what else to call it.

what about just spark.executor.port
(ala spark.driver.port
)

There's already a spark.executor.port
, and these two overlap

As of #1777 we log the name of the actor system when it binds to a port. The current name "spark" is super general and does not convey any meaning. For instance, the following line is taken from my driver log after setting `spark.driver.port` to 5001. ``` 14/08/13 19:33:29 INFO Remoting: Remoting started; listening on addresses: [akka.tcp://sparkandrews-mbp:5001] 14/08/13 19:33:29 INFO Remoting: Remoting now listens on addresses: [akka.tcp://sparkandrews-mbp:5001] 14/08/06 13:40:05 INFO Utils: Successfully started service 'spark' on port 5001. ``` This commit renames this to "sparkDriver" and "sparkExecutor". The goal of this unambitious PR is simply to make the logged information more explicit without introducing any change in functionality.

The goal of this PR is to allow users of Spark to write tight firewall rules for their clusters. This is currently not possible because Spark uses random ports in many places, notably the communication between executors and drivers. The changes in this PR are based on top of ash211's changes in apache#1107. The list covered here may or may not be the complete set of port needed for Spark to operate perfectly. However, as of the latest commit there are no known sources of random ports (except in tests). I have not documented a few of the more obscure configs. My spark-env.sh looks like this: ``` export SPARK_MASTER_PORT=6060 export SPARK_WORKER_PORT=7070 export SPARK_MASTER_WEBUI_PORT=9090 export SPARK_WORKER_WEBUI_PORT=9091 ``` and my spark-defaults.conf looks like this: ``` spark.master spark://andrews-mbp:6060 spark.driver.port 5001 spark.fileserver.port 5011 spark.broadcast.port 5021 spark.replClassServer.port 5031 spark.blockManager.port 5041 spark.executor.port 5051 ``` Author: Andrew Or <andrewor14@gmail.com> Author: Andrew Ash <andrew@andrewash.com> Closes apache#1777 from andrewor14/configure-ports and squashes the following commits: 621267b [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 8a6b820 [Andrew Or] Use a random UI port during tests 7da0493 [Andrew Or] Fix tests 523c30e [Andrew Or] Add test for isBindCollision b97b02a [Andrew Or] Minor fixes c22ad00 [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 93d359f [Andrew Or] Executors connect to wrong port when collision occurs d502e5f [Andrew Or] Handle port collisions when creating Akka systems a2dd05c [Andrew Or] Patrick's comment nit 86461e2 [Andrew Or] Remove spark.executor.env.port and spark.standalone.client.port 1d2d5c6 [Andrew Or] Fix ports for standalone cluster mode cb3be88 [Andrew Or] Various doc fixes (broken link, format etc.) e837cde [Andrew Or] Remove outdated TODOs bfbab28 [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports de1b207 [Andrew Or] Update docs to reflect new ports b565079 [Andrew Or] Add spark.ports.maxRetries 2551eb2 [Andrew Or] Remove spark.worker.watcher.port 151327a [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 9868358 [Andrew Or] Add a few miscellaneous ports 6016e77 [Andrew Or] Add spark.executor.port 8d836e6 [Andrew Or] Also document SPARK_{MASTER/WORKER}_WEBUI_PORT 4d9e6f3 [Andrew Or] Fix super subtle bug 3f8e51b [Andrew Or] Correct erroneous docs... e111d08 [Andrew Or] Add names for UI services 470f38c [Andrew Or] Special case non-"Address already in use" exceptions 1d7e408 [Andrew Or] Treat 0 ports specially + return correct ConnectionManager port ba32280 [Andrew Or] Minor fixes 6b550b0 [Andrew Or] Assorted fixes 73fbe89 [Andrew Or] Move start service logic to Utils ec676f4 [Andrew Or] Merge branch 'SPARK-2157' of github.com:ash211/spark into configure-ports 038a579 [Andrew Ash] Trust the server start function to report the port the service started on 7c5bdc4 [Andrew Ash] Fix style issue 0347aef [Andrew Ash] Unify port fallback logic to a single place 24a4c32 [Andrew Ash] Remove type on val to match surrounding style 9e4ad96 [Andrew Ash] Reformat for style checker 5d84e0e [Andrew Ash] Document new port configuration options 066dc7a [Andrew Ash] Fix up HttpServer port increments cad16da [Andrew Ash] Add fallover increment logic for HttpServer c5a0568 [Andrew Ash] Fix ConnectionManager to retry with increment b80d2fd [Andrew Ash] Make Spark's block manager port configurable 17c79bb [Andrew Ash] Add a configuration option for spark-shell's class server f34115d [Andrew Ash] SPARK-1176 Add port configuration for HttpBroadcast 49ee29b [Andrew Ash] SPARK-1174 Add port configuration for HttpFileServer 1c0981a [Andrew Ash] Make port in HttpServer configurable
