From e234ea1b49d30bb6c8b8c001bd98c43de290dcff Mon Sep 17 00:00:00 2001 From: Marcelo Vanzin Date: Thu, 6 Aug 2015 15:30:27 -0700 Subject: [SPARK-9645] [YARN] [CORE] Allow shuffle service to read shuffle files. Spark should not mess with the permissions of directories created by the cluster manager. Here, by setting the block manager dir permissions to 700, the shuffle service (running as the YARN user) wouldn't be able to serve shuffle files created by applications. Also, the code to protect the local app dir was missing in standalone's Worker; that has been now added. Since all processes run as the same user in standalone, `chmod 700` should not cause problems. Author: Marcelo Vanzin Closes #7966 from vanzin/SPARK-9645 and squashes the following commits: 6e07b31 [Marcelo Vanzin] Protect the app dir in standalone mode. 384ba6a [Marcelo Vanzin] [SPARK-9645] [yarn] [core] Allow shuffle service to read shuffle files. --- core/src/main/scala/org/apache/spark/deploy/worker/Worker.scala | 4 +++- core/src/main/scala/org/apache/spark/storage/DiskBlockManager.scala | 1 - 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/core/src/main/scala/org/apache/spark/deploy/worker/Worker.scala b/core/src/main/scala/org/apache/spark/deploy/worker/Worker.scala index 6792d3310b..79b1536d94 100755 --- a/core/src/main/scala/org/apache/spark/deploy/worker/Worker.scala +++ b/core/src/main/scala/org/apache/spark/deploy/worker/Worker.scala @@ -428,7 +428,9 @@ private[deploy] class Worker( // application finishes. val appLocalDirs = appDirectories.get(appId).getOrElse { Utils.getOrCreateLocalRootDirs(conf).map { dir => - Utils.createDirectory(dir, namePrefix = "executor").getAbsolutePath() + val appDir = Utils.createDirectory(dir, namePrefix = "executor") + Utils.chmod700(appDir) + appDir.getAbsolutePath() }.toSeq } appDirectories(appId) = appLocalDirs diff --git a/core/src/main/scala/org/apache/spark/storage/DiskBlockManager.scala b/core/src/main/scala/org/apache/spark/storage/DiskBlockManager.scala index 5f537692a1..56a33d5ca7 100644 --- a/core/src/main/scala/org/apache/spark/storage/DiskBlockManager.scala +++ b/core/src/main/scala/org/apache/spark/storage/DiskBlockManager.scala @@ -133,7 +133,6 @@ private[spark] class DiskBlockManager(blockManager: BlockManager, conf: SparkCon Utils.getConfiguredLocalDirs(conf).flatMap { rootDir => try { val localDir = Utils.createDirectory(rootDir, "blockmgr") - Utils.chmod700(localDir) logInfo(s"Created local directory at $localDir") Some(localDir) } catch { -- cgit v1.2.3
