Dear colleagues:
I use eclipse to develop some programs in hadoop, when
exceptions took place such as death cycle, I don't know how to
terminate it safely. Can you tell me? Thank you very much!

Dear colleagues:
I don't know how to insert new rows in a table, and there's
no insert method in HTable class. Can you tell me how to insert some
rows in a new table?
Thanks.

Dear colleagues;
I run the code as described below:
HBaseConfiguration conf = new HBaseConfiguration();
HBaseAdmin admin = new HBaseAdmin(conf);
HTableDescriptor[] tables = admin.listTables();
I see errors :
08/01/18 12:11:56 INFO ipc.Client: Retrying connect to server:
/127.0.1.1:60020. A
I have tried several times after locating hbase-site.xml into
${hadoop-home}/conf, but the same error exist . it connected to
0.0.0.0:6000 not to connect to my own IP .
the error the same as last time as below:
08/01/17 18:46:46 INFO ipc.Client: Retrying connect to server:
0.0.0.0:6. Alread
I have met this problem, When I run the code HBaseAdmin admin = new
HbaseAdmin(conf); the console print these messeages as below:
08/01/17 18:46:46 INFO ipc.Client: Retrying connect to server:
/0.0.0.0:6. Already tried 1 time(s).
08/01/17 18:46:47 INFO ipc.Client: Retrying connect to server:
Thank you for your help!
You metioned hadoop-0.16.* , but I still use hadoop-0.15 ,I can't see
hadoop-0.16.* in the http://lucene.apache.org/hadoop/releases.html,
and I haven't found the org.apache.hadoop.hbase.hql . .So I'm not sure
I use the correct edition.

in my map an
Dear colleague,
In the method of output.collect(key, value), I can set the
"value" as Text or IntWritable in the reduce function, but I can only
set it as IntWritable in the map function. Would you tell me why?
when I set the "value" as Text, the system output the error as follows :
java.io
Hi colleague,
After reading the API docs about hbase,I don't know how to
manipulate the hase using the java API .Would you please send me some
