* [SPARK-6027][SPARK-5546] Fixed --jar and --packages not working for ↵Tathagata Das2015-02-261-1/+28
| | | | | | | | | | | | | | | | | | KafkaUtils and improved error message The problem with SPARK-6027 in short is that JARs like the kafka-assembly.jar does not work in python as the added JAR is not visible in the classloader used by Py4J. Py4J uses Class.forName(), which does not uses the systemclassloader, but the JARs are only visible in the Thread's contextclassloader. So this back uses the context class loader to create the KafkaUtils dstream object. This works for both cases where the Kafka libraries are added with --jars spark-streaming-kafka-assembly.jar or with --packages spark-streaming-kafka Also improves the error message. davies Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #4779 from tdas/kafka-python-fix and squashes the following commits: fb16b04 [Tathagata Das] Removed import c1fdf35 [Tathagata Das] Fixed long line and improved documentation 7b88be8 [Tathagata Das] Fixed --jar not working for KafkaUtils and improved error message

* [SPARK-5993][Streaming][Build] Fix assembly jar location of kafka-assemblyTathagata Das2015-02-241-4/+0
| | | | | | | | | | | | | | | Published Kafka-assembly JAR was empty in 1.3.0-RC1 This is because the maven build generated two Jars- 1. an empty JAR file (since kafka-assembly has no code of its own) 2. a assembly JAR file containing everything in a different location as 1 The maven publishing plugin uploaded 1 and not 2. Instead if 2 is not configure to generate in a different location, there is only 1 jar containing everything, which gets published.

The Reliable Kafka Receiver commits offsets only when events are actually stored, which ensures that on restart we will actually start where we left off. But if the failure happens in the store() call, and the block generator reports an error the receiver does not do anything and will continue reading from the current offset and not the last commit. This means that messages between the last commit and the current offset will be lost. This PR retries the store call four times and then stops the receiver with an error message and the last exception that was received from the store.

| | | | | | | | | | | | | | | | | | | | test data. This fixes two sources of non-deterministic failures in this test: - wait for a receiver to be up before pushing data through MQTT - gracefully handle the case where the MQTT client is overloaded. There’s a hard-coded limit of 10 in-flight messages, and this test may hit it. Instead of crashing, we retry sending the message. Both of these are needed to make the test pass reliably on my machine.

* [SPARK-1010] Clean up uses of System.setProperty in unit testsJosh Rosen2014-12-304-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several of our tests call System.setProperty (or test code which implicitly sets system properties) and don't always reset/clear the modified properties, which can create ordering dependencies between tests and cause hard-to-diagnose failures. This patch removes most uses of System.setProperty from our tests, since in most cases we can use SparkConf to set these configurations (there are a few exceptions, including the tests of SparkConf itself). For the cases where we continue to use System.setProperty, this patch introduces a `ResetSystemProperties` ScalaTest mixin class which snapshots the system properties before individual tests and to automatically restores them on test completion / failure. See the block comment at the top of the ResetSystemProperties class for more details.

* [SPARK-2492][Streaming] kafkaReceiver minor changes to align with Kafka 0.8jerryshao2014-11-112-36/+5
| | | | | | | | | | | | | | | | | | | | | | Update the KafkaReceiver's behavior when auto.offset.reset is set. In Kafka 0.8, `auto.offset.reset` is a hint for out-range offset to seek to the beginning or end of the partition. While in the previous code `auto.offset.reset` is a enforcement to seek to the beginning or end immediately, this is different from Kafka 0.8 defined behavior. Also deleting extesting ZK metadata in Receiver when multiple consumers are launched will introduce issue as mentioned in [SPARK-2383](https://issues.apache.org/jira/browse/SPARK-2383). So Here we change to offer user to API to explicitly reset offset before create Kafka stream, while in the meantime keep the same behavior as Kafka 0.8 for parameter `auto.offset.reset`. @tdas, would you please review this PR?

| | | | | | | | | | | | | Due to maven bug https://jira.codehaus.org/browse/MNG-1378, maven could not resolve spark streaming classes required by the spark-streaming test-jar dependency of external/flume-sink. There is no particular reason that the external/flume-sink has to depend on Spark Streaming at all, so I am eliminating this dependency. Also I have removed the exclusions present in the Flume dependencies, as there is no reason to exclude them (they were excluded in the external/flume module to prevent dependency collisions with Spark).

Observing and comparing the dependency trees from Maven and SBT showed this. Spark depends on ZK 3.4.5 whereas Apache Kafka transitively depends on upon ZK 3.3.4. SBT decides to evict 3.3.4 and use the higher version 3.4.5. But Maven decides to stick to the closest (in the tree) dependent version of 3.3.4. And 3.3.4 does not have NIOServerCnxnFactory.
