Chukwa collector confronted with a NPE

Exception in thread "Thread-332" java.lang.NullPointerException

org.apache.hadoop.chukwa.datacollection.writer.SocketTeeWriter$Tee.run(SocketTeeWriter.java:136)

/10.32.149.15

And the 10.32.149.15 is our hadoop cluster.

This exception arises very frequently , every 5 mins.

But the collector seemed doesn't been influenced .

Why this exception arises? Is there something wrong with the hadoop?
