---------------------------------
hi Mike, that means Flume will execute 'HDFS flush/fsync' at each Sink
transaction?
> Retire hdfs.txnEventMax in HDFS sink

> The HDFS sink uses hdfs.txnEventMax in addition to hdfs.batchSize to control
> number of events taken in a transaction and also regularity of fsync()
> behavior separately. All other sinks use a single property batchSize to
> control both of these parameters.
> We should use the hdfs.batchSize parameter for both of these things so that
> the hdfs.txnEventMax parameter does nothing.
