Summary: N/A Job Tracking URL in Build WebUI
Key: KYLIN-1339
URL: https://issues.apache.org/jira/browse/KYLIN-1339
Project: Kylin
Issue Type: Bug
Components: Web
Reporter: Yerui Sun
Assignee: Zhong,Jason
By designing, the cuboid building steps on web ui has the url directed to the
job page on yarn.
In fact, the url can't be always retrieved successfully. The url is 'N/A'
sometimes, or added a prefix 'unsafe:' sometimes, or the right link sometimes.
With some debug log, founded that the url was fetched from status info, which
filled by job.getTrackingURL() in HadoopCmdOutput.getInfo() when check job
status in MapReduceExecutable. The job tracking url was 'N/A' at the first 20
seconds since job started, and became the right link after that. One possible
reason is that the tracking url is valid until AppMaster started, which started
slowly.
There's still one question, the job status checking was executed periodically,
and the status info should filled with job tracking url after some seconds
later, but the web ui link was not updated.
Some more digging is needed for this issue.
