Increment expects a long as per returned by Bytes.toBytes(long). ie:
8 bytes, big endian.
you put '1' array length 1.
when increment finds no value, it assumes '0'. if you want 0 based
counting dont put an initial value.

I that's the bug where disabling a table that was just split and still
has the parent entries in .META. puts it into a weird state. We can do
some deeper debugging to help you getting that table back but I
strongly suggest that you upgrade to 0.90.1 where the issue is fixed.
There's no backport
An hour to disable? That doesn't sound right at all :)
I would approach this problem like I generally do with HBase issue,
first check the master log for any weirdness regarding my problem (in
this case, grep for the table name).
Then I would look the region server log(s) of the nodes that were
I see the master is waiting and I see the exceptions but there's no
context and the timestamps don't match (what happened in the region
server at the time the second master took over), can you explain
exactly what was done to get in that state? Also could you please tell
use which hbase version
Hello,
I have a HBase cluster chock-full of data and would like to run canned reports
(i.e.,
reports known ahead of time), but also ad-hoc reports against that data.
Are there any open-source or commercial tools one can use?
Here's what I *think* I know so far, but please correct me wherever
We use the HBase+Hive integration here for ad-hoc queries, I don't
understand the data duplication you're talking about... when you
create an external table you can directly query your existing tables.
We run with the latest patch posted in HIVE-1634 since we have a lot
of binary values and I made
Hi J-D,
Yes, I'm interested in HBase-Hive integration.
Thanks for the pointer to the external tables. I was aware of that at some
point, but for some reason started thinking that data copying is necessary.
Are there any gotchas or serious limitations around this integration?
Thanks,
Otis
Sorry to jump in here but does HBase use Map/Reduce under the covers? I was
under the impression that HBase used the DFS of Hadoop but not Map/Reduce.
Thanks

You're right, and I don't see anything that contradicts that in
Consider a HBase cluster whose primary task is to ingest data, process
it with MR jobs, and store it back in some table(s). That's what the
cluster does today.
I was just wondering if when I did 'puts' or 'scans' in my HBase Client was
HBase using Map/Reduce to add/query the tables.
It doesn't, I'm 99.% sure that Otis referred to MR jobs that are
run by himself and not by HBase. Look at the HTable code, there's no
dependency on mapred or mapreduce.

We are using 0.20x hbase. We are seeing some big delays on the client's

are seeing about 20ms. The network delay is negligible. We have a about 250
threads per JVM each having its own HTable client handle. Reducing the
That's what I thought but being new I just wanted make sure so I can get a
better idea of the internals.

Otis,
There is early work on hbase replication happening. That might be useful to
firewall the load in the way that you are looking for.

The below looks like https://issues.apache.org/jira/browse/HBASE-3545.
The fix will be in 0.90.2. Try upgrading to 0.90.1 and patching in
