Otherwise it can happen that your Spark job does not proceed anymore. Currently, Apache Mesos only offers resources if there are at least 32 MB memory allocatable. But as Spark allocates memory only for the executor and cpu only for tasks, it can happen on high slave memory usage that no new tasks will be started anymore. More details can be found in [MESOS-1688](https://issues.apache.org/jira/browse/MESOS-1688). Alternatively use the "coarse-gained" mode, which is not affected by this issue. - # Running Alongside Hadoop You can run Spark and Mesos alongside your existing Hadoop cluster by just launching them as a diff --git a/repl/scala-2.10/src/test/scala/org/apache/spark/repl/ReplSuite.scala b/repl/scala-2.10/src/test/scala/org/apache/spark/repl/ReplSuite.scala index 529914a2b6..249f438459 100644 --- a/repl/scala-2.10/src/test/scala/org/apache/spark/repl/ReplSuite.scala +++ b/repl/scala-2.10/src/test/scala/org/apache/spark/repl/ReplSuite.scala @@ -281,7 +281,7 @@ class ReplSuite extends FunSuite { assertDoesNotContain("Exception", output) } - if (System.getenv("MESOS_NATIVE_LIBRARY") != null) { + if (System.getenv("MESOS_NATIVE_JAVA_LIBRARY") != null) { test("running on Mesos") { val output = runInterpreter("localquiet", """ diff --git a/repl/scala-2.11/src/test/scala/org/apache/spark/repl/ReplSuite.scala b/repl/scala-2.11/src/test/scala/org/apache/spark/repl/ReplSuite.scala index ed9b207a86..b3bd135548 100644 --- a/repl/scala-2.11/src/test/scala/org/apache/spark/repl/ReplSuite.scala +++ b/repl/scala-2.11/src/test/scala/org/apache/spark/repl/ReplSuite.scala @@ -289,7 +289,7 @@ class ReplSuite extends FunSuite { assertDoesNotContain("Exception", output) } - if (System.getenv("MESOS_NATIVE_LIBRARY") != null) { + if (System.getenv("MESOS_NATIVE_JAVA_LIBRARY") != null) { test("running on Mesos") { val output = runInterpreter("localquiet", """ |
