Hi,
I'm trying to restart Flume. My setup is:
Acro source => File channel 1 => HDFS sink
=> File channel 2 => Another HDFS sink
=> File channel 3 => File sink
But it seem to be doing replayLog for hours now, after seeing this
yesterday, I even tried setting use-fast-replay=true, but it didn't help.
Each file channel capacity is 100000000, is this too high for Flume? I
started on lower number but then it complained that the channel is getting
filled so I made it higher.
My log is repeatedly writing such lines:
08 Aug 2013 01:36:22,856 INFO [lifecycleSupervisor-1-1]

In attaching jstack output, I wasn't sure what the threads are doing but in
any case many of them seem to be waiting..
Any idea what I can do to make the server start?
Thanks
