Hi all,
I have a configuration with a file channel configured such that:
a1.channels.ch1.type = file
a1.channels.ch1.checkpointDir = /hadoop/user/flume/channels/checkpoint
a1.channels.ch1.dataDirs = /hadoop/user/flume/channels/data
a1.channels.ch1.capacity = 100000
a1.channels.ch1.transactionCapacity = 5000
It's been running since October 28th with no issues, but when I looked today in /hadoop/user/flume/channels/data I saw that the file channel was building up large files which had been processed and not deleting them:
[rdd@hadoop-kn-p2-m01 flume]$ ls -lh channels/data/
total 1.6G
-rw-r----- 1 rdd rdd 1.5G Oct 28 16:10 log-1
-rw-r----- 1 rdd rdd   47 Oct 28 16:10 log-1.meta
-rw-r----- 1 rdd rdd  72M Oct 31 16:28 log-2
-rw-r----- 1 rdd rdd   47 Oct 31 16:29 log-2.meta
It seems like for each day that data landed (we're still in testing so data not landing constantly) a data file has been created but not deleted when reading was completed.
Is this expected behaviour? Is there a way to stop large files building up and still use the file channel?
