Flume Not starting

Trying to run flume, getting below error org.apache.flume.node.Application --name a1 --conf-file /home/anitharao/flume-demo/example.conf
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/hdp/!/org/slf4j/impl/StaticLoggerBinder.class]

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property ‘log4j2.debug’ to show Log4j2 internal initialization logging.

this is my example.conf
a1.sources = r1
a1.sinks = k1
a1.channels = c1

Describe/configure the source

a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44448

Describe the sink

a1.sinks.k1.type = logger

Use a channel which buffers events in memory

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

Bind the source and sink to the channel

a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

running command like below
flume-ng agent --name a1 --conf-file /home/anitharao/flume-demo/example.conf
