Hi

Hi Chhaya,

Assuming you are at flume home directory, here is the command to start:

 bin/flume-ng agent -n agent -f conf/flume-conf.properties -c conf

Flume starts and runs with a maximum heap size of 20mb. If you are using batching, you may
run into out of memory error pretty quickly. To increase the heap size, rename the file  flume-env.sh.template
 to flume-env.sh in conf directory and uncomment the JAVA_OPTS line and edit the minimum and
maximum heap. Example: JAVA_OPTS="-Xms512m -Xmx1024m"

If "-c conf" is not specified at the end of the command, your flume-env.sh file will not be
taken into effect.


Cheers,

Joao
