-----------------------------------
Summary: NPE related to checkpointing when using FileChannel
Key: FLUME-1205
URL: https://issues.apache.org/jira/browse/FLUME-1205
Project: Flume
Issue Type: Bug
Components: Sinks+Sources
Affects Versions: v1.2.0
Environment: CentOS 5.6 x64
Reporter: Will McQueen
Priority: Critical
Fix For: v1.2.0
I'm seeing NPE when stopping the Flume agent, and then starting it up again.
I'm using this config file:
agent.channels = c1
agent.sources = r1
agent.sinks = k1
#
agent.channels.c1.type = FILE
#
agent.sources.r1.channels = c1
agent.sources.r1.type = NETCAT
agent.sources.r1.bind = c1123.hal.cloudera.com
agent.sources.r1.port = 41414
#
agent.sinks.k1.channel = c1
agent.sinks.k1.type = org.apache.flume.sink.hbase.HBaseSink
agent.sinks.k1.table = footable5
agent.sinks.k1.columnFamily = foocol5
#agent.sinks.k1.batchsize = 100
#agent.sinks.k1.serializer.rowPrefix = default
#agent.sinks.k1.serializer.incrementRow = incRow
#agent.sinks.k1.serializer.suffix = uuid
agent.sinks.k1.serializer.payloadColumn = paycol
agent.sinks.k1.serializer.incrementColumn = inccol
...and I'm seeing this error:
