> Currently, the AM writes the job-specific information to HDFS only after it finishes; the JHS needs this info to display anything. If the AM fails, this info is not written and the JHS fails to display anything for that job.
> While JHS on top of AHS might address this issue, it would be nice to have a solution in the interim.
