stack commented on HBASE-1048:
------------------------------
If we have to process 1000+ logs because of regionserver restart, cluster won't
come back on line for hours. Also, checking for logs to delete during roll of
log blocks all updates. Spinning through 1000+ blocks updates a long time.
> HLog: Found 0 logs to remove out of total 1450; oldest outstanding seqnum is
> 162297053 fr om region -ROOT-,,0

> Above was in tim sell log just before it OOME'd. 1450 log files are going to
> mess us up. Need to clear them. Catalog tables should probably keep up the
> old optional flush or, if N commit logs, schedule a flush on the region with
> the oldest sequent number.
> Bringing into 0.19.0. Gets in the way of our scaling.
