Billy Pearson commented on HBASE-433:
-------------------------------------
might also take a look at what point the master sees a region as crashed from a
region server
example
say I have a failed region server and master loads and saves restore logs for
each region
on the reopen of a region and say it replaying the logs and crashes
Would the master overwrite the old log file with a new one or would the master
not consider the region as part of the region server on a crash until it
receives an MSG_REPORT_PROCESS_OPEN message?
Should look in to this so we do not have a risk of over writing a restore log
file that has not successfully loaded and flushed to disk.
> region server should deleted restore log after successfull restore

> Project: Hadoop HBase
> Issue Type: Bug
> Components: regionserver
> Reporter: Billy Pearson
> Priority: Trivial
> Fix For: 0.2.0
>
>
> Currently we do not remove the restore log "oldlogfile.log" after we reopen a
> region after a crashed region server.
> Suggestion would be to remove after we successfully flush of all the edits to
> a mapfile
> so something like:
> replay log
> memcache flush
> deleted log
