Mike Percy commented on FLUME-2653:
-----------------------------------
Hmm, one more thing. I wonder what happens if you specify this in the
configuration file:
{code}
my_agent.sinks.my_hdfs_sink.hdfs.inUseSuffix =
{code}
Won't that achieve a similar effect? Maybe this patch is not needed, and we
already have this feature (but people just don't know how to use it)? I haven't
investigated this in depth but that question also needs to be answered.
Regarding the comment by [~yobibytes] about the Cloudera Manager validation,
someone from Cloudera should investigate whether that is a real Flume bug, a
Flume validation bug, or a Cloudera Manager validation bug. If I recall
correctly, Cloudera Manager relies on information from Flume itself for most of
its configuration validation. If it's a Flume-related bug, we can fix it here,
otherwise that needs to be handled elsewhere (not as part of the Apache Flume
project)

> At the moment, it doesn't seem possible to set the null/empty. We've tried

> We want the _in use_ file to have the same name as the _closed_ file, so we
