Hi Lars,
Is the async version available in hbase-0.20.6 ASF version? It is
still in development right?

Disabling a table simply takes time as all RSs need to report back

Hi Lars,
Great! Thanks!! Is there any downside to increasing this value to
too high?

If you up the config., the retry will be more tenacious. To be safer,
you could make it so you have a client config. and one used by the
servers. See conf/hbase-env.sh for HBASE_CONF_DIR for pointing at
alternate conf directories.
This disable/enable malarky will run better in 0.90.x

The REST gateway (Stargate) is a long lived client. :-)
It uses HTablePool internally so this will keep some warm table references
around in addition to the region location caching that HConnectionManager does
behind the scenes. (10 references, but this could be made configurable.)

Not just su.pr, but also stumbleupon.com which has the social layer.
We do have memcached in front of HBase. Regarding blog posts about our
setup, just search for stumbleupon hbase and you'll find tons. The
most recent presentation that's available online is my talk at Hadoop
World.

If you are game for deploying an instrumented jar, we could log client
lookups in .META. and try and figure if it profligate.

Did you set it up with TableMapReduceUtil?

If you use TableMapReduceUtil, then it's set to 2MB by default, but
looking at the RS logs the write buffer is
Thats great! Thanks. this will help us reduce network context
switching as we remove the need to pass a lot of uncompressed packets.

Hey guys,
I just want to get an idea about how everyone avoids these long GC pauses
that cause regionservers to die.
What kind of java heap and garbage collection settings do you use?
What do you do to make sure
We are at 35 TB now.

Interesting. The settings we tried earlier today slowed jobs significantly,
but no failures (yet). We're going to try the 512MB newSize and 60%

Btw, does it mean, I can send in a compressed query? Or only receive
compressed data from REST or both?
Jetty's GzipFilter only wraps response handling.
I tested to see if Jetty has some built in support for Content-Encoding: gzip
for PUT or POST and it appears not:
