lpstudy commented on HDFS-8193:
-------------------------------
Thanks for your great job about making erasure code native in HDFS.
I am working on proactive data protection in HDFS by incorporating hard drive
failure detection method based on collected SMART attributes into HDFS kernel
and scheduling disk warning process in advance and want to have erasure code
native supported by HDFS kernel instead of HDFS-RAID.
I have some questions below, but I don't know how to consult them , so I just
list my questions here and hope it won't bother you so much.
1, I am wonderring whether and where i can download the project source code you
are working on.
2, When this project will be accomplished, will it take a long time ?
3, Whether guys like me can join your group?
> Add the ability to delay replica deletion for a period of time

> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: namenode
> Affects Versions: 2.7.0
> Reporter: Aaron T. Myers
> Assignee: Zhe Zhang
>
> When doing maintenance on an HDFS cluster, users may be concerned about the
> possibility of administrative mistakes or software bugs deleting replicas of
> blocks that cannot easily be restored. It would be handy if HDFS could be
> made to optionally not delete any replicas for a configurable period of time.
