Hi,
You need to create your table with pre-split regions.
$hbase org.apache.hadoop.hbase.util.RegionSplitter -c 10 -f region_name
your_table
This command will pre-create 10 regions in your table using MD5 strings as
region boundaries.
You can also customize the splitting algorithm. Please see
Hi Otis,
This command might be what you want:
hadoop fs -dus /hbase

Beside the HBase side configuration, you need to add the following to your
ZOOKEEPER/conf/zoo.cfg, and then restart ZooKeeper will allow you to change the
40 secs.
maxSessionTimeout= 12
Details can be found here.

That is okay.
What do you get from the describe command?
hbase> describe 'cjjWaitHash'

If you DNS works well, you should not need to use hosts file.
Can you remove master and slave1 record from your /etc/hosts file and then try
a clean setup again?

Hi Sambit,
Are you specifying a local file system path on the command line?
Before invoking importtsv, you will need to copy your tsv files to HDFS at
first.

The NameNode keeps in safe mode might because it can not reach the block
reported ratio threshold as some files are corrupted.
You can use hadoop dfsadmin -safemode leave
to leave safe mode at first, and then hadoop fsck / -move or -delete to
move/delete inconsistent files.

Hi,
As mentioned in HBase Book, we can force a manual hlog splitting by:
hbase org.apache.hadoop.hbase.regionserver.wal.HLog --split
hdfs://example.org:8020/hbase/.logs/example.org,60020,1283516293161/
What's the use case of this manual splitting?
If RS is crashed, the hlog splitting will be tri
Hi Stack,
I have tested it using org.apache.hadoop.hbase.filte.PrefixFilter.
And the result is same when using my own filter.
So I created the following issue.
Please check the details at here.

Thanks.

Hi,
I has a MyFilter class extends FilterBase, and a MyInputFormat extends
hbase.mapred.TableInputFormat, the deprecated mapred APIs.
It seems that the filter will not be invoke when there are only a few
data in the table.
This is the code in my InputFormat's configure m
er.
Is there something wrong in my code?
I'm using HBase0.90.0 and have put MyFilter in HBase's classpath.
Thanks.

LogCleaner is running without replication being enabled
means that your hbase-default.xml is from an older version. Please
refresh it.

We don't have so many user yet now, so the version change of Hadoop is
not so difficult.
Thanks.
