Is scanning supported using partial of the row key?
if i have a row key as name + timestamp + id + type
can i scan the rows with start key as name + timestamp
will it fetch any rows from the base.I'm stuck up and it doesn't work.I'm
always getting null rows.
Can someone please help me.
thanks

Hi,
You can perform scan this way,
scan 'tablename', {STARTROW='name + start time stamp', ENDROW='name + end
time stamp'}
Idea is, you can scan with prefix values but if you want to scan with name
+ * + id, then I doubt.
Thanks

To know what takes your CPU,you can use java -Xprof to start the Java
Process.
It can give you a report what method takes most.

Hi all:
From blogs I know HTablePool class is like ConnectionPool.But when I use
method putTable() ,my IDE noticed me
The method putTable(HTableInterface) from the type HTablePool is
deprecated
Is this class has been abandon?Do there any class like HTablePool instead?
Hi
Don't use HTablePut.put() method, just HTable.close on the table you got
from pool when you no longer need it. Don't worry, the table will be put
back in the pool after you closed it.

sounds like your cpu is blocked waiting on your disks.
What does your cluster look like?
how many cores per node? how many spindles?

Sorry for the bad typing, Don't use HTablePool.putTable()...
The class is not abandoned from what I know, only the putTable method
should be avoided.

Hi All,
I am using cdh3u2. I am having problem accessing the table.jsp page from
the web interface of HBase cluster. Two days ago i was able to view HBase
table information with the help of table.jsp. But, after a cluster crash it
started giving the following error:
HTTP ERROR 404
Problem
There might be some issue with the table itself.
Can you issue get, scan from HBase shell ?
Please examine master / region server logs for relevant information.

Yes, everything works fine with the HBase shell. I even ran count on the
table which was having 32 million rows. So, apart from table.jsp everything
looks good.
Is there a place where i can find logs for jetty?

Hi all:
I'm trying to import data from oracle to hbase and now I have a problem.
In some tables,there have more than one primary key and they all use a
lot.
How to design the rowkey in these tables to make them searched quickly?
Presumably you mean there are more than one UNIQUE key (only one pk per
table, even in rdbms..)
Thats a core difference between rdbms and hbase: secondary indexes are not
suppoted per se in the latter. There are various options here, one of
which may be to:

Thanks for your suggestions,
and I have another question.
For example,in RDBMS I have 3 tables:orders,item,order_item
and in table order_item have two PK:order_id,item_id.
Usually,I use order_id to find item_id and use item_id to find orderid.
If I use order_id +_+ item_id to be the rowkey in
