--------------------------------------
Thanks Jingcheng. I am thinking to drop quarterly/yearly policy from the
current proposal to reduce the case described by Anoop.
the threshold proposal may not work as the time passes, there will be more
files and the threshold will be easily reached.
> Expand Mob Compaction Partition policy from daily to weekly, monthly and
> beyond

> Today the mob region holds all mob files for all regions. With daily
> partition mob compaction policy, after major mob compaction, there is still
> one file per region daily. Given there is 365 days in one year, at least 365
> files per region. Since HDFS has limitation for number of files under one
> folder, this is not going to scale if there are lots of regions. To reduce
> mob file number, we want to introduce other partition policies such as
> weekly, monthly to compact mob files within one week or month into one file.
> This jira is create to track this effort.
