shutdown order of hbase and hadoop

If hadoop is restarted when hbase is still running, hbase table(s) would be
corrupted.

Is it possible to make hbase tolerate hadoop restart ?

Thanks

Ride over (HDFS) restart is something I'll be addressing in the coming months.

Well one of its subtask (904) was assigned to andrew in february 2010,
I guess that means he's looking at it (or at least wants to).

But even before being able to ride over HDFS restarts, there's still a
lot of core work to do in HBase and we only have some many hours per
day ;)

I found HBASE-879 which has been inactive for 1 year and 5 months.

Can someone take a look at it again ?

Thanks

There is an outstanding issue over in the current down JIRA to address
this, make it so hbase can ride over FS restart.
