I did not realize I could use pre-built binaries on Windows. Thank you, I used this to grab the hadoop-common.jar from our existing Hadoop cluster and there are no startup errors now.
Thanks to you, Brock and Hari. -Paul ________________________________ From: Israel Ekpo [mailto:[email protected]] Sent: Wednesday, April 10, 2013 12:07 PM To: [email protected] Subject: Re: FileChannel on Windows Paul, If Flume 1.3.1 is what you are looking for, you don't have to build it from source. You can just download it directly from the site. Its already released. Paul Chavez <[email protected]> wrote: Hello, I've been using flume on Windows to send logs to an avro source for awhile now, using the AvroClient class. I'm now trying to get a full agent running to hopefully leverage the spoolDir and httpSource functionality. Part of my requirements is a persistent channel so I'm attempting to get a config running the utilizes the fileChannel. I followed the instructions at http://mapredit.blogspot.com/2012/07/run-flume-13x-on-windows.html to build flume, same as I did for the AvroClient. However it seems I need some HDFS libraries. Can anyone point me to instructions for building the JAR(s) I need to get this working? Currently I'm running into the following exception: 10 Apr 2013 11:50:29,317 INFO [lifecycleSupervisor-1-0] (org.apache.flume.channel.file.FileChannel.start:285) - Starting FileChannel fc_Default { dataDirs: [c:\flume_data\log] }... 10 Apr 2013 11:50:29,317 ERROR [lifecycleSupervisor-1-0] (org.apache.flume.channel.file.FileChannel.start:314) -
