-----------------------------------
Summary: Partial registration to external shuffle services on Mesos
Key: SPARK-23286
URL: https://issues.apache.org/jira/browse/SPARK-23286
Project: Spark
Issue Type: Bug
Components: Mesos, Shuffle
Affects Versions: 2.2.0
Reporter: Igor Berman
As continuation of https://issues.apache.org/jira/browse/SPARK-12583
I see that registration to external shuffle services is partial only(i.e. the
application is not registered to all external shuffle services where executors
are running for given framework/application)
Seems like some updates either not handled or lost. Probably the first option
is more relevant due to registering only when statusUpdate handles TaskStatus
that equals RUNNING

Setup:
{code:java}
spark.shuffle.service.enabled = true
spark.dynamicAllocation.enabled = true
spark.dynamicAllocation.executorIdleTimeout = 20s
spark.shuffle.service.port = 7337
spark.dynamicAllocation.maxExecutors = 50
spark.dynamicAllocation.minExecutors = 2
spark.dynamicAllocation.cachedExecutorIdleTimeout = 300s
spark.default.parallelism = 3000
spark.sql.shuffle.partitions = 3000
spark.cores.max = 400
spark.driver.maxResultSize = 8g
spark.executor.memory = 70g
spark.mesos.coarse = true
spark.worker.timeout = 150000
spark.network.timeout = 1200s
spark.executor.heartbeatInterval = 600s
spark.hadoop.cloneConf = true
spark.memory.fraction = 0.75
spark.memory.storageFraction = 0.1{code}
Here is trace extraction which "proves" that only 2 registration happened,
however at this point several(>2) Mesos tasks(spark executors) were running
