Will McQueen created FLUME-1259:
-----------------------------------
Summary: Flume throws OutOfMemory error when sending data from
netcat to avro source (negative test case)
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
Here's the exception:

I'm wondering if there's some kind of validation of incoming avro format that
we can do that would prevent this error.
