Improve delim / delimMode used by tail and tailDir to allow inclusion or
exclusion of part of the delimiter
-----------------------------------------------------------------------------------------------------------
Key: FLUME-1042
URL: https://issues.apache.org/jira/browse/FLUME-1042
Project: Flume
Issue Type: Improvement
Components: Sinks+Sources
Affects Versions: v0.9.4
Reporter: Steve Stogner
Priority: Minor
I want stack dumps in a log file sent as a single event to a collector.
>From the user manual:
"Finally, this example tails a file and uses the regex "\n\d\d\d\d" as a
delimiter and appends the delimiter to the next event. This could be used to
gather lines from a stack dump in a log file that starts with four digits (like
a year from a date stamp).
tail("file", delim="\\n\\d\\d\\d
d", delimMode="next")"
The output using the configuration above includes the entire delimiter,
including the newline. However, I want the date stamp part of the delimiter to
be included in the output, but the newline part of the delimiter to be excluded
from the output. Perhaps the delim and delimMode properties could be enhanced
to allow users to include or exclude parts of the delimiter based on matching
groups in the regex.
