Re: Hadoop jars
Generally you need to install it separately On Nov 19, 2012, at 2:07 PM, Rahul Ravindran rahu...@yahoo.com wrote: Hi, I was exploring how I could look to deploy Flume into our cluster. The binary package available at http://flume.apache.org/download.html does not appear to have the hadoop jar files which are needed by the HDFS sink. I would expected it to be packaged in the lib folder. Is this deliberate? Is there a different binary which I could look to download for the hadoop jars? Thanks, ~Rahul.
Re: Hadoop jars
Currently, unfortunately, i dont think there is any such documentation. A very general answer would be..Normally this list would depend on the source/sink/channel you are using. I think it would be nice if the user manual did list these external dependencies for each component. I am not the expert on HDFS sink.. but i dont see why it would depend on anything more than HDFS itself. -roshan On Mon, Nov 19, 2012 at 2:18 PM, Rahul Ravindran rahu...@yahoo.com wrote: Are there other such libraries which will need to be downloaded?

Re: Hadoop jars
Easiest way is to install cdh binary and point your flume's classpath to it.

Re: Hadoop jars
Flume installs all required binaries, except for Hadoop (and the dependencies it would pull in) and HBase. This is because Flume, like most other Hadoop ecosystem components is meant to work against binary incompatible versions of Hadoop (Hadoop-1/Hadoop2). So instead of packaging hadoop jars with Flume, we expect Hadoop to be available on the machines you are running Flume on. Once you install Hadoop you should not have any dependency issues. Same is true for HBase. Hari -- Hari Shreedharan On Monday, November 19, 2012 at 2:33 PM, Mohit Anchlia wrote: Easiest way is to install cdh binary and point your flume's classpath to it.

Re: Hadoop jars
Thanks for the responses. Good to know that the only external dependencies are Hadoop and Hbase. We will deploy those components only on boxes which are going to have those sinks set up.

Re: Hadoop jars
Unfortunately, the FileChannel too has a hadoop dependency - even though the classes are never used. So you need the hadoop jars (and they should be added to FLUME_CLASSPATH in flume-env.sh or HADOOP_HOME/HADOOP_PREFIX should be set) on machines which will use the FileChannel. The channel directly does not depend on Hadoop anymore, but still needs them in the class path because we support migration from the older format to new format.

Re: Hadoop jars
That is unfortunate. Is it sufficient if I package just hadoop-common.jar or is the recommended way essentially doing an apt-get install flume-ng which will install the below # apt-cache depends flume-ng flume-ng Depends: adduser Depends: hadoop-hdfs Depends: bigtop-utils My concern is that hadoop-hdfs brings in a ton of other stuff which will not be used in any box except the one running the hdfs sink.
