Subject Re: what are the libraries needed for flume log4jappender
Date Wed, 23 Jan 2013 20:03:10 GMT
Mike,

I am importing the project into eclipse using maven, but the project has
issues in the legacy-sources module.

Description Resource Path Location Type
AvroFlumeEvent cannot be resolved to a type NettyAvroRpcClient.java
/flume-ng-sdk/src/main/java/org/apache/flume/api line 189 Java Problem


Runtime issues are with 1.3.1
1.   If I include just ng-core, I run into issues of FlumeException not
found.

Classpath:
C:\ServiceManager\workspace\mongodb\Mongodb\bin;C:\test\log4j-1.2.16.jar;C:\apache\apache-flume-1.3.1-bin\lib\flume-ng-core-1.3.1.jar;C:\apache\apache-flume-1.3.1-bin\lib\flume-ng-log4jappender-1.3.1.jar
log4j:WARN Error during default initialization
java.lang.NoClassDefFoundError: org/apache/flume/FlumeException
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)
at java.lang.Class.getConstructor0(Unknown Source)
at java.lang.Class.newInstance0(Unknown Source)


2.   If I include ng-core, and ng-sdk, I run into the following exception.
Classpath:
C:\ServiceManager\workspace\mongodb\Mongodb\bin;C:\test\log4j-1.2.16.jar;C:\apache\apache-flume-1.3.1-bin\lib\flume-ng-core-1.3.1.jar;C:\apache\apache-flume-1.3.1-bin\lib\flume-ng-log4jappender-1.3.1.jar;C:\apache\apache-flume-1.3.1-bin\lib\flume-ng-sdk-1.3.1.jar

Appreciate your help,
