Here is the code change in EmbeddedAgentConfiguration:
/**
* Avro sink which can send events to a downstream avro source. This is the
* only supported sink for Embedded Agents.
*/
public static final String SINK_TYPE_AVRO = SinkType.AVRO.name();
public static final String SINK_TYPE_HBASE = SinkType.HBASE.name();
public static final String SINK_TYPE_HDFS = SinkType.HDFS.name();
private static final String[] ALLOWED_SINKS = {
SINK_TYPE_AVRO,
SINK_TYPE_HBASE,
SINK_TYPE_HDFS
};
This is my code with configurations:
Map<String, String> properties = new HashMap<String, String>();
properties.put("channel.type", "file");
properties.put("sinks", "hdfs1");
properties.put("hdfs1.type", "hdfs");
properties.put("hdfs1.path", "hdfs://lax07.unx.sas.com:8020/tmp");
properties.put("processor.type", "default");
agent = new EmbeddedAgent(“myAgent”);
agent.configure(properties); <-- This statement causes the
exception below
org.apache.flume.FlumeException: Expected one source and got 0

org.apache.flume.agent.embedded.EmbeddedAgent.doConfigure(EmbeddedAgent.java:160)

Can you send the code you used?
Thanks,

I added in an HDFS sink. But, I am getting this FlumeException: Expected one

The only source for the embedded agent is 'embedded', correct? Not sure how to
proceed from here.
Need help.

Try a bit of hacking in
org.apache.flume.agent.embedded.EmbeddedAgentConfiguration class, and add HBase
Sink to allowed sinks in the section
private static final String[] ALLOWED_SINKS = {
SINK_TYPE_AVRO,
// Add Hbase sink here <<<
};
See if it works and let us know.
HTH!
