Hi,
    I am new to HBase & I wanted to Cluster HBase on 2 nodes.I used 
hadoop-0.20.2 and hbase-0.94.1.I started hadoop cluster as well as HBase on
the name-node side. They started fine.

Master-b4 :-
13624 QuorumPeerMain
13806 HMaster
13237 NameNode
13431 SecondaryNameNode
13529 JobTracker

Slave-b4 :-
12986 HRegionServer
12679 DataNode
12825 TaskTracker

when I try to create tables in HBase shell I got the following error. 

> create 't1','date'

ERROR: org.apache.hadoop.hbase.PleaseHoldException:
org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

Here is some help for this command:
Create table; pass table name, a dictionary of specifications per
column family, and optionally a dictionary of table configuration.
Dictionaries are described below in the GENERAL NOTES section.
Examples:

  hbase> create 't1', {NAME => 'f1', VERSIONS => 5}
  hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}
  hbase> # The above in shorthand would be the following:
  hbase> create 't1', 'f1', 'f2', 'f3'
  hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000,
BLOCKCACHE => true}
  hbase> create 't1', 'f1', {SPLITS => ['10', '20', '30', '40']}
  hbase> create 't1', 'f1', {SPLITS_FILE => 'splits.txt'}
  hbase> # Optionally pre-split the table into NUMREGIONS, using
  hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
  hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO =>
'HexStringSplit'}

*
http://master-b4:60010/master.jsp* shows 

"You are currently running the HMaster without HDFS append support enabled.
This may result in data loss. Please see the HBase wiki for details. "

And I added following lines in hdfs-site.xml and hbase-site.xml files, but
still, I am getting same problem .

<property>
<name>dfs.support.append</name>
<value>true</value>
</property>

Please help me.

Thanks
