Hadoop：jar丢失查找

在运行Hadoop与HBase常出现某些jar包没有添加进工程，导致类找不到，下面对该问题做了一个统计分析，结果如下表所示：

报错	相应缺失的包
java.lang.ClassNotFoundException: com.google.common.base.Preconditions;	guava-11.0.2.jar
java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory	commons-logging.jar
java.lang.ClassNotFoundException: org.apache.commons.collections.map.UnmodifiableMap	commons-collection.jar
java.lang.ClassNotFoundException: org.apache.hadoop.util.PlatformName	hadoop-auth.jar
java.lang.ClassNotFoundException: org.slf4j.LoggerFactory	slf4j-api-1.7.5.jar
java.lang.ClassNotFoundException: org.apache.zookeeper.KeeperException	zookeeper-3.4.6.jar
java.lang.ClassNotFoundException: org.apache.hadoop.hbase.protobuf.generated.MasterProtos$MasterService$BlockingInterface	hbase-protocol-1.0.1.1.jar
java.lang.NoClassDefFoundError: org/apache/htrace/Trace	htrace.jar
java.lang.ClassNotFoundException: com.google.protobuf.ServiceException	protobuf-java-2.5.0.jar
java.lang.ClassNotFoundException: io.netty.channel.EventLoopGroup	netty-all-4.0.23.Final.jar
java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils	commons-lang.jar;
java.lang.NoClassDefFoundError: org/apache/commons/configuration/Configuration	commons-configuration.jar

java.lang.ClassNotFoundException: org.apache.commons.cli.ParseException	commons-cli-1.2.jar
java.lang.ClassNotFoundException: org.htrace.Trace	htrace-core-3.0.4.jar

根据以上提示，到自己的Hadoop及hbase中查询相关的包添加进工程即可
