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. #1 on it's own should cover most cases though -- This message was sent by Atlassian JIRA (v6.3.4#6332)
