--------------------------------
Summary: Connection key is hard to read
Key: SPARK-4934
URL: https://issues.apache.org/jira/browse/SPARK-4934
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.1.1
Reporter: Hong Shen
When I run a big spark job, executor have a lot of log,
14/12/23 15:25:31 INFO network.ConnectionManager: key already cancelled ? sun.nio.ch.SelectionKeyImpl@52b0e278
java.nio.channels.CancelledKeyException
at org.apache.spark.network.ConnectionManager.run(ConnectionManager.scala:310)
at org.apache.spark.network.ConnectionManager$$anon$4.run(ConnectionManager.scala:139)
It's hard to know which connection is cancelled. maby we can change to
logInfo("Connection already cancelled ? " + con.getRemoteAddress(), e)
