Re: Flume error in FIleChannel
There was no disk space issue and we ran fsck on the disks and did not find any file corruption issue. Did not see anything weird at that point in time either

Looks like the file may have been corrupted. Can you verify if you are out of disk space or can see something that might have caused the data to be corrupted?

Hi,
>  We are using CDH flume 1.3 (which ships with 4.2.1). We see this error in our flume logs in our production system and restarting flume did not help. Looking at the flume code, it appears to be expecting the byte to be an OPERATION, but is not. Any ideas on what happened?
