[jira] Created: (HADOOP-4434) Improve log rotation and reduce
communication between agent and logging process, make agent more fault
tolerant
Improve log rotation and reduce communication between agent and logging process, make agent more fault tolerant
---------------------------------------------------------------------------------------------------------------
Key: HADOOP-4434
URL: https://issues.apache.org/jira/browse/HADOOP-4434
Project: Hadoop Core
Issue Type: Improvement
Environment: Redhat Enterprise Linux 4.5, Java 6
Reporter: Eric Yang
- Chukwa Agent does not handle rotated log correctly. The current design requires the logging process to pause the agent, rotate the log, then resume the log streaming. The three communication between the running process and chukwa agent could become a problem when either or one of the process is down. The implementation should be able to detect log rotation in the chukwa agent.
- Chukwa Agent should detect and prevent the same log being streamed more than once.
- Chukwa Agent should synchronize data streaming addition when picking up the check point file.
