> Flume throws OutOfMemory error when sending data from netcat to avro source

> Key: FLUME-1259
> URL: https://issues.apache.org/jira/browse/FLUME-1259
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources
> Affects Versions: v1.2.0
> Environment: RHEL 6.2 64-bit
> Reporter: Will McQueen
> Priority: Minor
> Fix For: v1.2.0
>
>
> This is a negative test case.
> I mistakenly sent data from netcat to an avro source, and Flume through an
> OutOfMemory error. I sent just 5 one-character events using interactive
> netcat (nc localhost 41414) and the following config file:
> agent.channels = c1
> agent.sources = r1
> agent.sinks = k1
> #
> agent.channels.c1.type = MEMORY
> #
> agent.sources.r1.channels = c1
> agent.sources.r1.type = AVRO
> agent.sources.r1.bind = 0.0.0.0
> agent.sources.r1.port = 41414
> #
> agent.sinks.k1.channel = c1
> agent.sinks.k1.type = LOGGER
