From 4d99b95ad0d0c7ef909c8e492ec45e94cf0189b4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E9=83=AD=E5=B0=8F=E9=BE=99=2010207633?= Date: Sun, 30 Apr 2017 09:06:25 +0100 Subject: [PATCH] [SPARK-20521][DOC][CORE] The default of 'spark.worker.cleanup.appDataTtl' should be 604800 in spark-standalone.md MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What changes were proposed in this pull request? Currently, our project needs to be set to clean up the worker directory cleanup cycle is three days. When I follow http://spark.apache.org/docs/latest/spark-standalone.html, configure the 'spark.worker.cleanup.appDataTtl' parameter, I configured to 3 * 24 * 3600. When I start the spark service, the startup fails, and the worker log displays the error log as follows: 2017-04-28 15:02:03,306 INFO Utils: Successfully started service 'sparkWorker' on port 48728. Exception in thread "main" java.lang.NumberFormatException: For input string: "3 * 24 * 3600" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) at java.lang.Long.parseLong(Long.java:430) at java.lang.Long.parseLong(Long.java:483) at scala.collection.immutable.StringLike$class.toLong(StringLike.scala:276) at scala.collection.immutable.StringOps.toLong(StringOps.scala:29) at org.apache.spark.SparkConf$$anonfun$getLong$2.apply(SparkConf.scala:380) at org.apache.spark.SparkConf$$anonfun$getLong$2.apply(SparkConf.scala:380) at scala.Option.map(Option.scala:146) at org.apache.spark.SparkConf.getLong(SparkConf.scala:380) at org.apache.spark.deploy.worker.Worker.(Worker.scala:100) at org.apache.spark.deploy.worker.Worker$.startRpcEnvAndEndpoint(Worker.scala:730) at org.apache.spark.deploy.worker.Worker$.main(Worker.scala:709) at org.apache.spark.deploy.worker.Worker.main(Worker.scala) **Because we put 7 * 24 * 3600 as a string, forced to convert to the dragon type, will lead to problems in the program.** **So I think the default value of the current configuration should be a specific long value, rather than 7 * 24 * 3600,should be 604800. Because it would mislead users for similar configurations, resulting in spark start failure.** ## How was this patch tested? manual tests Please review http://spark.apache.org/contributing.html before opening a pull request.
