Question

here moved snapshot jar in lib folder getting this error after running flume command, ie

user@ubuntu:~/hadoop_store/apache-flume-1.4.0-bin/bin$ ./flume-ng agent -n TwitterAgent -c conf -f ../conf/twitter1.conf

also tried

user@ubuntu:~/hadoop_store/apache-flume-1.4.0-bin/bin$ ./flume-ng agent -n TwitterAgent -c conf -f /home/user/hadoop_store/apache-flume-1.4.0-bin/conf/twitter1.conf

cause in one of similar question it was mentioned such, here is what exactly its saying

Here is my twitter1.conf file,is there any error in this as such

# Naming the components on the current agent. 
TwitterAgent.sources = Twitter 
TwitterAgent.channels = MemChannel 
TwitterAgent.sinks = HDFS

# Describing/Configuring the source 
TwitterAgent.sources.Twitter.type = org.apache.flume.source.twitter.TwitterSource
TwitterAgent.sources.Twitter.consumerKey = ###
TwitterAgent.sources.Twitter.consumerSecret = ###

TwitterAgent.sources.Twitter.accessTokenSecret = ###
TwitterAgent.sources.Twitter.keywords = lalalala

Unable to figure out whats the problem here

在flume / lib文件夹中添加flume-sources-1.0-SNAPSHOT.jar并用Twitter4j2.2.6.jar文件（核心文件，媒体文件和流文件）替换Twitter4j3.0.3.jar
