Hi,
I want to put only 200MB data to a HBase table.
Just use a single thread to put 1MB data in a time.
So, there are 200 job in turn.
It occured WARN zookeeper.ZooKeeperWrapper: Failed to create /hbase,
while it run to around the 20th job.
I found that table has just one regin.
I wonder whether these tight job will make that region server choke.
About the region split, I want to know when the table's region will be
splitted.
Is its threshold setting in hbase-default.xml?
Following are a snippet of my code about putting my data to hbase, anything
can improve it?
table1 = new HTable("MyTable");
table1.setAutoFlush(false);
table1.setWriteBufferSize(1024*1024*12);
Put p = new Put(Bytes.toBytes(rs.getString(KeyColumn)));
p.add(Bytes.toBytes(FamColumn),
Bytes.toBytes("content"),Bytes.toBytes(json));
table1.put(p);
table1.flushCommits();
table1.close();
My cluster is only 3 PC with (1G,1G,2G RAM ,2 core CPU )
3 region server
3 ZK quorum server
We'll enlarge our cluster to 12PCs with 8G RAM.
Thanks
Fleming

Please respond to
hbase-user
What do you mean by quick way? You can use the api to put data into it
through a standalone java program or you can use a MR job to do it..
