Subject Exception in thread "SinkRunne​r-PollingR​unner-Defa​ultSinkPro​cessor" on writing to HDFS sink
Date Mon, 28 Oct 2013 20:02:35 GMT
Hi,
 
I am using the latest flume build 1.4 along with hadoop 2.2.0 to collect twitter stream and
write to HDFS sink. However, on writing to HDFS I get the following error:
 
2013-10-28 09:41:23,481 (SinkRunner-PollingRunner-DefaultSinkProcessor) [ERROR - org.apache.flume.sink.hdfs.HDFSEventSink.process(HDFSEventSink.java:422)]
process failed
