spark 1.4.0 java.lang.NoSuchMethodError: java.lang.NoSuchMethodError
提问于 2015-06-24 17:59:52
我使用的是spark 1.4.0 /Hadoop2.6.0(仅用于hdfs)，在运行Scala SparkPageRank示例SparkPageRank时遇到以下错误：
Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.elapsedMillis()J

以下信息可以起到帮助作用：
$ find ./spark -name *.jars | grep guava
./lib_managed/bundles/guava-16.0.1.jar
./lib_managed/bundles/guava-14.0.1.jar示例/pu.xml文件的一部分：
...
<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>
...实际上，这个类似乎不包含有问题的方法：
$ 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 boolean isRunning;
private long elapsedNanos;

public static com.google.common.base.Stopwatch createUnstarted();

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);
}我想更好地理解这个问题，如果可能的话，学习如何解决这个问题:-)

方法elapsedMilis()已在番石榴16中删除(或计划删除-无论如何，清单上没有此名称的方法)。
据我所知，应该有类似于番石榴16中的TimeUnit.MILLISECONDS，或者您可以通过diving1000000000.0手动转换。
