Subject Re: Query regarding adaptor for binary files
Date Fri, 04 Feb 2011 20:54:19 GMT

Yes, the chunk size is configurable. I think
chukwaAgent.fileTailingAdaptor.maxReadSize is the option you want to

Chukwa should not alter any of your data and should send every byte at
least once, appropriately tagged so that you can recover the exact
original file.
