使用hdfs作为接收器时，NoSuchMethod错误

时间：2013-09-04 02:36:04

标签： hadoop flume

我正在尝试使用HDFS配置水槽作为接收器。

这是我的flume.conf文件：

agent1.channels.ch1.type = memory

agent1.sources.avro-source1.channels = ch1
agent1.sources.avro-source1.type = avro
agent1.sources.avro-source1.bind = 0.0.0.0
agent1.sources.avro-source1.port = 41414

agent1.sinks.log-sink1.type = logger


agent1.sinks.hdfs-sink.channel=ch1
agent1.sinks.hdfs-sink.type=hdfs
agent1.sinks.hdfs-sink.hdfs.path=hdfs://localhost:9000/flume/flumehdfs/
agent1.sinks.hdfs-sink.hdfs.fileType = DataStream
agent1.sinks.hdfs-sink.hdfs.writeFormat = Text
agent1.sinks.hdfs-sink.hdfs.batchSize = 1000
agent1.sinks.hdfs-sink.hdfs.rollSize = 0
agent1.sinks.hdfs-sink.hdfs.rollCount = 10000
agent1.sinks.hdfs-sink.hdfs.rollInterval = 600

agent1.channels = ch1
agent1.sources = avro-source1
agent1.sinks = log-sink1 hdfs-sink

我的hadoop版本是：

Hadoop 0.20.2
Subversion https://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.20 -r 911707

Flume版本是：

apache-flume-1.4.0

我已将这两个jar文件放在flume / lib目录中

hadoop-0.20.2-core
hadoop-common-0.22.0

我把hadoop-common jar放在那里因为我在启动水槽剂时遇到以下错误：

我缺少一些配置或jar文件？

3 个答案:

答案 0 :(得分：2)

我最近在解决类似（虽然不完全相同）的问题时，我想起了两个可能对您有帮助的解决方案。

首先，你正在运行一个非常旧的Hadoop版本。它目前在（稳定版）1.2.1版本，2010年2月发布了0.20.2。我记得遇到一个用户遇到0.2x.x类似问题的线程，并建议他升级。

我的问题最终通过安装正确的java版本来解决。我认为需要JDK 1.6或更高版本（至少对于新版本的Hadoop而言）。对于CentOS，“yum install java-1.6.0-openjdk-devel”修复了我的完美。

对不起，我现在不能提供更多。我会尝试找到我之前阅读的相关主题并再次回复，但同时也许会给你一个开始的地方。如果没有别的，请回复你的java -version，这可能有助于进一步的故障排除。

答案 1 :(得分：1)

这些是我为解决问题而添加的罐子：

hadoop-core-1.0.4.jar
commons-configuration-1.6.jar
commons-httpclient-3.0.1.jar
jets3t-0.6.1.jar
commons-codec-1.4.jar

注意：使用hadoop 1.2.1时我没有添加任何额外的jar

答案 2 :(得分：0)

对于那些目前正在使用带有Flume 1.4的HDP 2.2并且你收到这样的错误的人：我只是通过用/ usr / hdp中的更新版本替换/ flume / lib中的hadoop-common.jar来修复它/文件夹（您的路径可能会有所不同）
