----------------------------------------
Summary: archive-logs tool may miss applications
Key: MAPREDUCE-6480
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6480
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.8.0
Reporter: Robert Kanter
Assignee: Robert Kanter
MAPREDUCE-6415 added a tool to archive aggregated logs into HAR files. It
seeds the initial list of applications to process based on apps which have
finished aggregated, according to the RM. However, the RM doesn't remember
completed applications forever (e.g. failover), so it's possible for the tool
to miss applications if they're no longer in the RM.
Instead, we should do the following:
# Seed the initial list of apps based on the aggregated log directories
# Make the RM not consider applications "complete" until their log aggregation
has reached a terminal state (i.e. DISABLED, SUCCEEDED, FAILED, TIME_OUT).
#2 will allow #1 to assume that any apps not found in the RM are done
aggregating. #2 on it's own should cover most cases though
