------------------------------------
Summary: FileChannel Log error message when there is no write
permission
Key: FLUME-1302
URL: https://issues.apache.org/jira/browse/FLUME-1302
Project: Flume
Issue Type: Improvement
Components: Sinks+Sources
Reporter: Mubarak Seyed
Priority: Minor
FileChannel Log instance tries to create files (checkpoint and data) and fails
when specified directory for flume user (or user one that used to start flume
agent) doesn't have write permission. It would be fine if we improve the error
message at
{code}
Preconditions.checkArgument(
checkpointDir.isDirectory() || checkpointDir.mkdirs(), "CheckpointDir "
+ checkpointDir + " could not be created");
{code}
{code}
