spark 1.4.0 java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.elapsedMillis()J

I'm using spark 1.4.0 / hadoop 2.6.0 (just for hdfs) and when running the Scala SparkPageRank example (examples/src/main/scala/org/apache/spark/examples/SparkPageRank.scala), I encounter the following error:

I'm not extremely familiar with java, but it seems that it's a guava version issue

The following information could be helpfup:

$ find ./spark -name *.jars | grep guava
./lib_managed/bundles/guava-16.0.1.jar
./lib_managed/bundles/guava-14.0.1.jar


part of the examples/pom.xml file:

...
<dependency>
<groupId>org.apache.cassandra</groupId>
<artifactId>cassandra-all</artifactId>
<version>1.2.6</version>
<exclusions>
<exclusion>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
</exclusion>
...


And indeed it seems that the class does not contain the problematic method:

$ javap -p /mnt/spark/examples/target/streams/\$global/assemblyOption/\$global/streams/assembly/7850cb6d36b2a6589a4d27ce027a65a2da72c9df_5fa98cd1a63c99a44dd8d3b77e4762b066a5d0c5/com/google/common/base/Stopwatch.class

Compiled from "Stopwatch.java"
public final class com.google.common.base.Stopwatch {
private final com.google.common.base.Ticker ticker;
private boolean isRunning;
private long elapsedNanos;
private long startTick;
public static com.google.common.base.Stopwatch createUnstarted();
public static com.google.common.base.Stopwatch createUnstarted(com.google.common.base.Ticker);
public static com.google.common.base.Stopwatch createStarted();
public static com.google.common.base.Stopwatch createStarted(com.google.common.base.Ticker);
public com.google.common.base.Stopwatch();
public com.google.common.base.Stopwatch(com.google.common.base.Ticker);
public boolean isRunning();
public com.google.common.base.Stopwatch start();
public com.google.common.base.Stopwatch stop();
public com.google.common.base.Stopwatch reset();
private long elapsedNanos();
public long elapsed(java.util.concurrent.TimeUnit);
public java.lang.String toString();
private static java.util.concurrent.TimeUnit chooseUnit(long);
private static java.lang.String abbreviate(java.util.concurrent.TimeUnit);
}


I would like to understand better the issue, and if possible learn how to fix it :-)

Answer

The method elapsedMilis() has been removed in Guava 16. (Or was planned to be removed - anyway there is no method with this name on your listing.)

As far I remember there should be something like TimeUnit.MILLISECONDS in guava 16, or you can convert manually by divading 1000000000.0.
