Description

In a 3 node cluster, flume agent was installed on all hosts. The following configs were used

agent.sources = pstream
agent.channels = memoryChannel
agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.capacity = 1000
agent.sources.pstream.channels = memoryChannel
agent.sources.pstream.type = exec
agent.sources.pstream.command = python /tmp/print_stream.py 100 10000
agent.sinks = hdfsSink
agent.sinks.hdfsSink.type = hdfs
agent.sinks.hdfsSink.channel = memoryChannel
agent.sinks.hdfsSink.hdfs.path = hdfs://tmp/flumetest1/
agent.sinks.hdfsSink.hdfs.fileType = DataStream
agent.sinks.hdfsSink.hdfs.writeFormat = Text
agent.sinks.hdfsSink.hdfs.rollCount = 30

When the host is clicked on, we should see graph sections for that agent. However there are exceptions in console log and white page.
Exceptions:
