Will McQueen updated FLUME-1175:
--------------------------------
Priority: Critical (was: Major)
> RollingFileSink complains of Bad File Descriptor upon a reconfig event
> ----------------------------------------------------------------------
>
> Key: FLUME-1175
> URL: https://issues.apache.org/jira/browse/FLUME-1175
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources
> Affects Versions: v1.2.0
> Environment: CentOS 6.2 64-bit
> Reporter: Will McQueen
> Priority: Critical
> Fix For: v1.2.0
>
>
> Steps:
> 1) Create a config file that looks something like this:
> agent.channels = c1
> agent.sources = r1
> agent.sinks = k1
> #
> agent.channels.c1.type = MEMORY
> #
> agent.sources.r1.channels = c1
> agent.sources.r1.type = SEQ
> #
> agent.sinks.k1.channel = c1
> agent.sinks.k1.type = FILE_ROLL
> agent.sinks.k1.sink.directory = /var/log/flume-ng
> agent.sinks.k1.sink.rollInterval = 0
> 2) Start the Flume NG agent
> 3) touch the config file so that a reconfig event is triggered within 30 secs
> 4) tail the output file to observer the sequence generator events:
> tail -f /var/log/flume-ng/XXXXXXXXXXXX
> 5) Notice that the flow suddenly stops at the reconfig event (within 30 secs
> after touching the config file). Flow doesn't continue. The flume log shows a
> Bad File Descriptor error for the RollingFileSink:
> 2012-05-03 01:34:34,806 (SinkRunner-PollingRunner-DefaultSinkProcessor)
> [ERROR - org.apache.flume.SinkRunner$PollingRunner.run(SinkRunner.java:160)]
