What if you enable blockcache ?

I don't think there is HA because Sandeep using Hadoop-1.0.2.
@Sandeep, did you check GC logs?

It is difficult to guess the reason behind this outage without the logs.
Can we have a look at them? (pastebin). Did you configure HA for namenode?
Did it failover to standby?

Hi,
Couple of hours back all of sudden NameNode of our production cluster got
stopped responding, due to this our HBase also stopped responding(as expected).
Here mysterious thing is we unable to get any reason for NameNode interruption.
I went through all log files of NameNode and I couldn't find

Subject: Re: Hbase Filter for RDBMS IN and AND query operation
Yes,
Applying Filter List with Pass ALL
ValueFilter would filter on the value of any qualifier and
SingleColumnValueFilter can filter on a specific column.
You can combine the two with a FilterList with MUST_PASS_ALL.
I agree with JM, though, that you should give Phoenix a try.

Hi Job,
first off some questions :)
How many regions are you accessing?
What type of query is this (get or scan)?
How many handlers have you configured?
What does you hardware look like (how many cores, etc)?
Is the data all in the blockcache?
If not, what does the disk IO look like?
Are the clien
Take a look at bin/rolling-restart.sh where you will see various options.

You mean installation folder where HBase binaries are expanded ? You can
use separate folders for .7 and .13.

Hi everyone,
I have in mind upgrading my productive cluster from 0.94.7 to 0.94.13.
Rolling upgrade is recommended (http://hbase.apache.org/upgrading.html) .
What is the step by step for that? I couldn't find it anywhere.

Yes,
Applying Filter List with Pass ALL containing two filters for name and flag
and iteratively adding it(previous filter list) to another filter list with

Hum.
Phoenix guys will most probably reply that Phoenix is the solution for that
;) And I will probably agree with them.
I don't see any filter which can do that within a single call.

The need is too broad. You need to do through the HBase jmx metrics, ands
machine metrics to see what is your bottleneck.

Hi, All!
Recently, I just test the Client write performance with HBase Java API.
I think the performance X-factor is :
1) client buffer size;
2) server memstore size;
But when i did the test, I have the result is :
1) As the client buffer size increase with 2M, 4M, 8M, 16M, 32M, and the write

How can we configure Hbase inorder to perform multythreading/parallel query
faster .
These are some bits from my analysis:
