-----------------------------------
See HBASE-2234 for the HBase version of this.
> HDFS sink should poll for # of active replicas. If less than required, roll

> Key: FLUME-1916
> URL: https://issues.apache.org/jira/browse/FLUME-1916
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources
> Affects Versions: v1.3.1
> Reporter: Mike Percy
> Fix For: v1.4.0
>
>
> Add functionality to the HDFS sink which constantly polls the number of
> replicas for files being written. If the number of replicas drops below 3 (or
> specified number), it should immediately close the HDFS output file and start
> a new file that should be able to create a pipeline with the correct number
> of replicas.
> This is the same behavior taken by HBase for its write-ahead log (WAL) and
> should help us avoid hitting the more complex corner cases around failed
> close() calls.
