setting FLUME_IDENT_STRING based on $USER is not robust
-------------------------------------------------------
Key: FLUME-770
URL: https://issues.apache.org/jira/browse/FLUME-770
Project: Flume
Issue Type: Bug
Components: Shell
Affects Versions: v0.9.4
Reporter: Roman Shaposhnik
Assignee: Roman Shaposhnik
Priority: Minor
Fix For: v0.9.5
The following bit of code from flume-daemon.sh fails to produce the correct
result under sudo-type of execution:
{noformat}
if [ "$FLUME_IDENT_STRING" = "" ]; then
export FLUME_IDENT_STRING="$USER"
fi
{noformat}
This is because $USER is not always set for shell. A more robust solution would
be to use the output of id -nu
