ema, eg: one table with rowkey as
A_B_time, another as B_A_time, when query B%, we just query table rowkey
B_A_time that just one small-scan, and not need for query table row
A_B_time with multi_scans.
Hope helpful for U.

cheBlocks(false), if the query will not query
repeat.
And remember let a certain start and end, even if as a PrefixScan(sometimes
just write start but not end, it maybe scan the whole bottom half of the
table), and let the section smaller with query more faster.

Yes, You are right.
We should consider the real range for the rowkey, just a thinking way to
struct the start and end, I am sorry somebody misguided by me.

As I know, zookeeper 3.4.2 is not a stable version.
Where is that written?
The website http://zookeeper.apache.org/releases.html said:
About zookeeper 3.4.3, it is a beta release.
And about zookeeper 3.4.2, it is an alpha release.
0.92? Can hbase 0.92 and
zookeeper 3.3 work well?

I don't know why sometime hbase resolve the node3 to eth0 192.168.1.13.
Is there somewhere that is used to resolve the dns name:node3?

How can I recover this table 'mytable'?
Thanks,
Jameson Li.
org.apache.hadoop.hbase.regionserver.HRegionServer: Worker:
MSG_REGION_CLOSE: mytable,,1302077037075
And also I have created/put/deleteall/disable/drop anohter table 'mytable1':
create 'mytable', {NAME='colfam:', COMPRESSION='lzo'}
Everything goes well.
But so strangely about the table 'mytable'.
Thanks,
Jameson Li.
