Hi
I would like to filtering rows that contain specific value at specific
{family, qualifier}.
For example, if my table contains the following lines, the cells are of the
form {fam, qual, val}
Row 1 : {fam-1, col0, val1}, {fam-1, col1, val11}
Row 2 : {fam-1, col0, val11}, {fam-1, col1, val21}
Would SingleColumnValueFilter serve your need ?
Cheers

Hello,
We have a requirement to determine whether a PUT will create a new row or
update an existing one. I looked at using preBatchMutate in a co-processor and
have the code below.
Few things I need to ask:
1) Is there a more efficient way of doing this?
2) Will region.getClosestRowBefore() add

Any update on this error? i tried Pseudo-Distributed mode But i still have
error

Here is some help for this command:

Here is the method in JniBasedUnixGroupsMapping which appears in stack
trace:
native static void anchorNative();
It is a native method.
Which hadoop release are you using ? How did you install it ?
Cheers

Hey folks,
How do I remove a dead region server?.I manually failed over the hbase
master but this is still appearing in master UI and also on the status
command that I run.
Thanks,
Nishan
Nishanth,
In my experience the only way I have been able to clear the dead region
servers is to restart the master daemon.

Thanks Pere. I just did that and still has the dead region server showing

in hbase and seeing few issues.Below is the stack trace I am seeing.

St.Ack,
I think you're side stepping the issue concerning schema design.
Since HBase isn't my core focus, I also have to ask since when has heap sizes
over 16GB been the norm?
(Really 8GB seems to be quite a large heap size... )

Hi,
I am implementing disaster recovery for our Hbase cluster and had one quick

There are many blog posts and articles about people turning for 16GB
heaps since java7 and the G1 collector became mainstream. We run with 25GB
heap ourselves with very short GC pauses using a mostly untuned G1
collector. Just one example is the excellent blog post by Intel,

I wasn’t saying St.Ack’s post wasn’t relevant, but that its not addressing the
easiest thing to fix. Schema design.
IMHO, that’s shooting one’s self in the foot.
You shouldn’t be using versioning to capture temporal data.

Hi,
I am using Hbase MultiTableInputFormat to compare 2 tables: Table1 (7
million), Table2 (30 million).
In the driver, i am passing to scans ( without any filters). In my mapper i
am doing a compare and writing the summary in Reducer.
Any settings specific to this scenario that might speed up

Hi
In one old project where usernames and passwords are in RDB, we need
authenticate users from RDB before they can go via REST to HBase.
So the first thing was Knox.
