Flafka !!!

Hi guys,


Again, here i am in my journey to deploy Kafka+Flume. I'm receiveing data from Kafka, which is working pretty good (as always !!!). But at Flume Agent i got the following message:


isFileClosed is not available in the version of HDFS being used. Flume will not attempt to close files if the close fails on the first attempt java.lang.NoSuchMethodException: org.apache.hadoop.fs.LocalFileSystem.isFileClosed(org.apache.hadoop.fs.Path)

at java.lang.Class.getMethod( at org.apache.flume.sink.hdfs.BucketWriter.getRefIsClosed( at at org.apache.flume.sink.hdfs.BucketWriter.append( at org.apache.flume.sink.hdfs.HDFSEventSink.process( at org.apache.flume.sink.DefaultSinkProcessor.process( at org.apache.flume.SinkRunner$ at


I'm using CDH 5.3 with Kerberos.

Any clue ????

Re: Flafka !!!

This basically suggests that Flume won't retry closing files. This is just an info message, and nothing to worry about. In CDH 5.4, this feature was redone to not retry closing files anyway.

There is nothing you need to worry about here.
