Excellent. If i trigger the balancer, should this start to help or only for
future region creation?

Ok. I forced the balancer run and am not seeing anything after a few
minutes. Master logs isn't showing anything. Should I look at the RS ones
instead?

Hi Alok,
xyz$ regex is enough to get the desired result. It will perform better
than ^.*xyz$. ^.*xyz$ is doing some unnecessary work.

Hi,
I've played with the feature to expose RDD via Thrift to enable JDBC
access. (Spark 1.2)
val eventsView = sqlContext.createSchemaRDD(eventSchemaRdd)
eventsView.registerTempTable(Events)
HiveThriftServer2.startWithContext(sqlContext)
This works all fine.
Now, my understanding is you

I don't think HBase mailing list is appropriate to search for an OCR.

What is hbase's philosophy in this? Does it allow some degree of data
loss?
HBase doesn't allow data loss, in the sense that HBase never chooses on
its own to be less than fully durable. However, our client API does allow
users to submit mutations with different durability guarantees.

Using TableInputFormat directly will have better scalability than HS2.
Better still, use TableSnapshotInputFormat to work from a snapshot (since
RDDs are immutable anyway).

Hi,
I was on 0.98 running PerformanceEvaluation. randomRead or sequentialRead
all show good read counts on the table regions.
filterScan shows exactly the same as you had.
Looking at the code. It could be as expected. The filter has no matching
returns, so the region server is in

It seems WAL.append() in hbase, the javadoc says:
* * Append a set of edits to the WAL. The WAL is not flushed/sync'd after
this transaction*
* * completes BUT on return this edit must have its region edit/sequence
id assigned*
* * else it messes up our unification of mvcc and

AFAIK, OCR requires training if you want to get a high quality recognition.
and it's not easy to have a model that suits all styles of hand writings

Hi Hongbin,
The WAL class is used internally to the region server. Typically an HBase
write operation will first call WAL.append() with the data, then later,
after releasing locks, call WAL.sync() to ensure that the data for that
write has been synced to be durable before returning to the client
Thanks Ted. We are putting this in the hbase-site.xml for the Master?

So Serega, when does your application finally close the HConnection? Or the

In your scene, per servlet used a HConnecton object, so the response for 5
rpm is so easy.
If these servlets should share the only one HConnecton object, whether or not
the response latency for 5 rpm would increase?
Hi Andrey,
thanks for your reply, I found them very inspiring.
I'm curious about the scheme you described: It looks to me you've sharded
your data into separate regions, are you fixing the number of these regions?
If yes, each of the growing region will spawn lots of compactions while
