>             Project: Flume
>          Issue Type: Documentation
>    Affects Versions: 1.6.0
>            Reporter: Johny Rufus
>            Assignee: Ferenc Szabo
>            Priority: Minor
>             Fix For: 1.9.0

>
> Flume transactions will fail/retry continuously when the Channel's 
> transactionCapacity < batchSize of the source/sink
> We should document this requirement in the User guide, as part of the 
> channel's transactionCapacity parameter.
> This is trivial, but it may be reasonable to document this as lot of newbies 
> would set the batchSize parameter of the source/sink to a higher value (>100) 
> and would forget to set the transactionCapacity of the channel and the 
> default value of 100 would kick in and cause issues.
