hello, list,
I am now setting up a HBase cluster using HBase version
0.20.2. But I have met some problems which I googled a lot and got no
answer.
Please help me.
I modified the Hbase-site.xml and copy the whole directory to
another machine.
Using one as the master, after I started the hbase server, I
CAN see Hmaster / HQuorumPeer / HRegionServer running on Master
and HQuorumPeer / HRegionServer running on the slave node.
Here is what's weird:
I can enter the hbase shell on master node, but on the other
region server I cannot execute any command, a "list" command would cause a
list of exception.
10/01/11 21:16:46 DEBUG client.HConnectionManager$ClientZKWatcher: Got
ZooKeeper event, state: SyncConnected, type: None, path: null
10/01/11 21:16:46 DEBUG zookeeper.ZooKeeperWrapper: Read ZNode /hbase/master
got 127.0.1.1:60000
10/01/11 21:16:46 INFO client.HConnectionManager$TableServers: getMaster
attempt 0 of 5 failed; retrying after sleep of 2000
java.net.ConnectException: Connection refused

org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:206)
at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:404)
I can create table in the master node's Hbase shell, but there
sometime is some exception like:
10/01/12 06:08:15 DEBUG client.HConnectionManager$TableServers:
locateRegionInMeta attempt 2 of 5 failed; retrying after sleep of 2000
org.apache.hadoop.hbase.client.NoServerForRegionException: No server address
listed in .META. for region t3,,1263305290760

org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegionInMeta(HConnectionManager.java:668)

org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:594)
at
org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:557)
But after this I can use list to see that the table HAS BEEN BUILT
inside the hdfs.
the Hbase-site.xml I used:
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
