Hello,
I'm setting up a jenkins job for hbase, building branch 0.95 (from github)
under jdk 6.
However sometimes the build pasts, sometimes does not. Several tests are
likely to fail, such as:
org.apache.hadoop.hbase.ipc.TestDelayedRpc.testDelayedRpcImmediateReturnValue
org.apache.hadoop.hbase.i
If you enable aggregation coprocessors you can use aggreation client which is
more faster than normal count from shell.

org.apache.hadoop.hbase.coprocessor.ColumnInterpreter,
org.a
Stack & Enis:
Your responses clear my thoughts. Thanks.

Another option is Phoenix (https://github.com/forcedotcom/phoenix),
where you'd do
SELECT count(*) FROM my_table

Is there a faster way to get the count of rows in a HBase table
(potentially a huge one)? I am looking for ways other than the 'count'
shell command or any Pig script? Thanks.

Hi,
HDFS has two interfaces for durability: hflush and hsync:
Hflush() : Flush the data packet down the datanode pipeline. Wait for
ack’s.
Hsync() : Flush the data packet down the pipeline. Have datanodes execute
FSYNC equivalent. Wait for ack’s.
There is some work on adding a Durability API in
Here's my config. This is for a different file system so it might provide
some insight compared with the examples online (
http://hbase.apache.org/book/example_config.html)
You need the fully qualified name for the hbase.rootdir.
hbase.master
Or, even better, if someone has a sample hbase-site.xml file
that I can see, that would be even better :) .

Ok, I finally got HBase to work. With the current networking configs
and then just tried to run it with the default configs. I didn't change the
path to the directory, which I think I was messing up in hbase-site.xml.
One more question, how should the syntax look like in this thing? If I

hi, folks,
I am wonderring how to get an overview of the replication of all tables of
a cluster.
For example, I can get individual table/columnfamily info by describing the
table
hbase(main):003:0> describe 'usertable'
DESCRIPTION
ENABLED
{NAME => 'usertable', FAMILIES => [{NAME => 'family

Ok, it's obvious that this is a networking issue. I'm running on CentOS
and the hostname file is not in /etc, it's located in /etc/sysconfig/network
instead.
This is how that file looks like at the moment:
NETWORKING=yes
HOSTNAME=ysg.connect
/etc/hosts is like this:
127.0.0.1 localhost ysg.c
Just curious, but what's zookeeper.sh in the bin directory of HBase?

Over in HBASE-8626, Jean-Marc and Andrew voiced the opinion that the
current behavior may not be a bug.

What do you think ?

Hi Tian-Ying,
I don't think there is already a JIRA for that. The idea was to open a new
one and ask for HBCK to be able to fix that. Can you do that?
Do you have an easy way to reproduce your issue? Like by manually creating
files in HDFS or something like that?

Section 2.1.3.3 says that 1.0.4 has a working durable sync. But when I
check the source code of DFSClient.DFSOutputStream's sync method, I
