Hello,
I have used the command ./hbase
org.apache.hadoop.hbase.mapreduce.Export 'test'
http://localhost:8020/test to export the data content from the test
table. And I can see the exported content from my hdfs folder,
hdfs://localhost/test/part-m-0. I have tried 2 commands to read
the content
I noticed the problem is that somehow I lost the data from hdfs. The
code is ok.
Regards!

Hello,
One HFile consists of many blocks. Suppose we have two blocks, b1 and
b2. The size of each block is 2K. In b1, we have two key-value pairs,
whose keys are t1 and t2, separately. Each key-value pair is 1K. So
the b1 is full. Suppose that now we insert a new tuple which key is
also t1. The HB
ile.Writer hwriter = new HFile.Writer(fs, new
Path("hdfs://localhost:8020/test"), 2, (Compression.Algorithm)null,
null);
the data is stored in the hdfs.
regards!

Hello,
I wrote a single program to directly write data content to HFile.
Hbase is installed as pseudo-mode.
here is my code:
public static void putData() throws Exception{
FileSystem fs = new RawLocalFileSystem();
fs.setConf(new Configuration());

Hello,
I read some articles which mention before the client connect to the
master node, he will first connect to the zookeeper node and find the
location of the root node. So, my question is that the node which
stores the root information is different from master node or they are
the same node?

I have already disabled ipv6 and close the firewall, but I still get
the same problem. :(

Hallo,
I tried the pseudo distribution mode of HBase. The Hadoop version is
0.20.2. I configured the hbase-site.xml as
hbase.rootdir
hdfs://localhost:9000/hbase
dfs.replication
1
as same as in core-site.xml and hdfs-site.xml files of Hadoop, separately.
I can succe
