so I delete the corrpupt .logs files. OK, fine no more issue there. But a
handful of regions in a very large table (2000+ regions) are offline (".META."
says offline=true).
How do I go about trying to get the region online, and how come restarting
hbase has no effect (region still offline).
Tried 'hbck -fix', no effect. Hbck simply lists the table as "inconsistent".
Would appreciate any advice on how to resolve this.
Thanks,
geoff

Well, if its a log no longer used, then you could just delete it.
That'll get rid of the fsck complaint (True, logs are not per table so
to be safe you'd need to flush all tables -- this would get all edits
that the log could be carrying out into the filesystem into hfiles).
