-Simple HDFS Sink file rolling question please.
Chris Neal 2013-03-21, 20:21
I have an ExecSource running a tail -F on a bunch of log files that get
rotated nightly by log4J. I want my HDFS Sink to roll them when log4J
rolls them. I tried setting all the "roll" parameters to 0, thinking a new
file handle from the ExecSource would cause the current file in HDFS to be
closed, and a new file to be created, but I'm seeing only the new file
created, and the previous days file is still there as a .tmp file, unclosed.
I was wondering what configuration would achieve the behavior I'm after?
I was thinking a rollInterval of 24 hours, but wouldn't that cause HDFS to
roll the file at a different time than log4J rolled it?
Thanks for the time :)
Here is my HDFS Sink setup currently:
# hdfs-hadoopjt01_1-sink properties
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.type = hdfs
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.rollInterval = 0
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.rollSize = 0
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.rollCount = 0
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.batchSize = 10000
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.threadsPoolSize = 8
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.rollTimerPoolSize = 5
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.codeC = GzipCodec
hadoopjt01.sinks.hdfs-hadoopjt01_1-sink.hdfs.fileType = CompressedStream
