Dear all,
I application run well with HBase. But when I deploy my application to 10
instances, the eleventh application not run.
Maybe HBase have limit connection per IP?
How can I fix my problem?
I use zookeeper dump to see connection from my server to Hbase server. It
show 10 connection.
My HB
,f1:c -Dimporttsv.bulk.output=output
t1 input
In that, 't1', 'f1' is table and family in HBase.
No data write in 'output' folder.
Could you give me some advice?
Thank you in advance.

Dear all,
I want to import data from Cassandra to HBase.
I think the way maybe:
Customize ImportTsv.java for read Cassandra data file (*.dbf) and convert
to HBase data files, and use completebulkload tool
Could you give me show advice?
Thank a lot for support.
Dear all,
I want to design Follower schema like Twitter. I have 2 design
Design 1:
userId{//rowkey
followerId: time,

Design 2 :
[userId][followerId]{//rowkey

I have 2 question:
1. Does HBase support scan data of rowkey by column?
2. Which design is better? I think that

Dear all,
When I stop and start HBase server, HTable (org.apache.hadoop.hbase.client)
throw exception.
Here is my code test:
HTable ht = new HTable(config, "T1");
byte[] row = Bytes.toBytes(1);
Get get = new Get(row);
Result result = ht.get(get);

But client always retry 12 times.
Could you help me?

Dear all,
I set up my HBase server in standalone mode.
Can HBase Client (from another machine) connect to this HBase server?
How can I do that?
A lot of people have the same question. But I did not find correct answer.
Thank a lot for support.
Dear all,
Which is better design between more row key and more columns?
And another question, does HBase support query column like function
get_slice of Cassandra?
Thank a lot for support.
