I am not sure if this is the cause of your problem, but you seem to have a
mismatch for the hostname header key
between your interceptor (myhostname) and your sink (host).

Hi,
I am using flume1.2 version. Having the following configuration.
agent1Test1.sources = seqGenSrc
agent1Test1.channels = memoryChannel
agent1Test1.sinks = loggerSink
# For each one of the sources, the type is defined
agent1Test1.sources.seqGenSrc.type = exec
agent1Test1.sources.seqGenSrc.command= tail -f /tomcat/logs/catalina.out
agent1Test1.sources.seqGenSrc.interceptors = hostInterceptor
agent1Test1.sources.seqGenSrc.interceptors.hostInterceptor.type =
org.apache.flume.interceptor.HostInterceptor$Builder
agent1Test1.sources.seqGenSrc.interceptors.hostInterceptor.hostHeader =
myhostname
# The channel can be defined as follows.
agent1Test1.sources.seqGenSrc.channels = memoryChannel
# Each sink's type must be defined
agent1Test1.sinks.loggerSink.type = hdfs
agent1Test1.sinks.loggerSink.hdfs.path = hdfs://host:8020/data/%{host}/Logs
agent1Test1.sinks.loggerSink.hdfs.fileType = DataStream
#Specify the channel the sink should use
agent1Test1.sinks.loggerSink.channel = memoryChannel
# Each channel's type is defined.
agent1Test1.channels.memoryChannel.type = memory
# Other config values specific to each type of channel(sink or source)
# can be defined as well
# In this case, it specifies the capacity of the memory channel
agent1Test1.channels.memoryChannel.capacity = 1000
Gettting the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError:
