[jira] [Updated] (MAPREDUCE-6415) Create a tool to combine
aggregated logs into HAR files
[ https://issues.apache.org/jira/browse/MAPREDUCE-6415?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Kanter updated MAPREDUCE-6415:
-------------------------------------
Attachment: MAPREDUCE-6415_branch-2_prelim_002.patch
MAPREDUCE-6415_prelim_002.patch
The prelim_002 patch:
- Uses {{YARN_SHELL_ID}} from YARN-3950 instead of parsing {{CONTAINER_ID}}
- Runs 'hadoop archive' and the FileSystem commands from a Java program, so we can limit the JVM startup cost

> While we wait for YARN-2942 to become viable, it would still be great to improve the aggregated logs problem. We can write a tool that combines aggregated log files into a single HAR file per application, which should solve the too many files and too many blocks problems. See the design document for details.
> See YARN-2942 for more context.
