Mike Percy commented on FLUME-2037:
-----------------------------------

Hey Hari I am still getting failures on this test.

Applied the patch, then

{noformat}
$ cd flume-ng-channels/flume-file-channel
$ for i in $(seq 1 100); do echo $i; mvn test 
-Dtest="TestFileChannelRestart#testDataFilesRequiredByBackupNotDeleted" || 
break; done
{noformat}

I just found out that surefire supports that syntax... pretty sweet... anyway I 
am getting the following error message:

{noformat}
$ head -10 
./target/surefire-reports/org.apache.flume.channel.file.TestFileChannelRestart.txt

I didn't investigate much, but I hacked up the patch a little and got this 
error message out of it after it failed on the 29th run:

{noformat}
