Is there a benefit to restarting a regionserver in an OSGi container versus
restarting a Java process?
Was that rhetorical?
Absolutely.
Think of a production environment where you are using HBase to serve data in
real time.

Isn't the time to restart and the steps necessary more or less the same? Or
will the objects that hold the in memory state survive across the reload?
Will they still share a classloader (maintain equality tests)? What if the
implementation / bundle version changes? We are taking about an upgrade
Thanks Ted Michael.

Hi,
I don't see any methods returning streams in the Java client HTable :
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HTable.html
That means we need to use the thrift client to get streams ?

I assume you want to scan the table:
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HTable.html#getScanner(byte[])
Can you point out which thrift client methods provide streaming capability ?
Thanks

No I don't want to scan a table, I want a stream of one result. In case for

With thrift it is up to the client to deal with the response, so in theory
you can build a client which returns streams.
But when I look at the current implementation of thrift for node for
Well,
What happens when you restart the RS?
Suppose I'm running a scan on a completely different table and you restart the
RS?
What happens to me?
I havent thought through the whole problem, but you need to put each table's CP
in to its own sandbox.
(There's more to it and would require
These approaches all sound somewhat brittle and unlikely to be relied on
for a production system (more here:
https://issues.apache.org/jira/browse/HBASE-8607). Sounds like a rolling
restart is the best option in the near/medium term. Our pain points are
more around how to get to the point

Yeah, no streaming API in our current client (nor does our thrift client
give you a streaming API).

Hi,
Today I faced a power outage. 4 computers stayed up. The 3 ZK servers,
the Master, the NN and 2 DN/RS. They was on UPS.
While everything was going back up... Guess what... I faced a 2nd one!
After bringing HBase up, about 97% of my data was missing. (19M rows
in my main table)
I ran HBCK
Are you saying 97 % data was lost or was it offlined until the region
servers came back up ?

Sure, but that wont change the fact that Coprocessors should go under a massive
rewrite.
You're hitting a problem that Sybase faced while Informix (datablades) didn't
when it came to running end user code within the engine.
But I'm dating myself...

Hi,
I have a weird error in a cluster I'm checking Replication with.
I have two clusters set up, each on its own DC (different continents). Each
has 1 master, and 3 RS.
I've done all required setup, started replication and pushed in some data
into the master. I had an issue where the slave
15 matches
