Getting "Table Namespace Manager not ready yet" while creating table in hbase

I tried to create a table but it is giving me below error. Kindly check

hbase(main):003:0> create 't1', 'f1'

ERROR: java.io.IOException: Table Namespace Manager not ready yet, try
again later

Here is some help for this command:
Creates a table. Pass a table name, and a set of column family
specifications (at least one), and, optionally, table configuration.
Column specification can be a simple string (name), or a dictionary
(dictionaries are described below in main help output), necessarily
including NAME attribute.
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', {NAME => 'f1', CONFIGURATION =>
{'hbase.hstore.blockingStoreFiles' => '10'}}

Table configuration options can be put at the end.
Examples:

  hbase> create 't1', 'f1', SPLITS => ['10', '20', '30', '40']
  hbase> create 't1', 'f1', SPLITS_FILE => 'splits.txt', OWNER => 'johndoe'
  hbase> create 't1', {NAME => 'f1', VERSIONS => 5}, METADATA => { 'mykey'
=> 'myvalue' }
  hbase> # Optionally pre-split the table into NUMREGIONS, using
  hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
  hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO =>
'HexStringSplit'}
  hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO =>
'HexStringSplit', REGION_REPLICATION => 2, CONFIGURATION =>
{'hbase.hregion.scan.loadColumnFamiliesOnDemand' => 'true'}}

You can also keep around a reference to the created table:

  hbase> t1 = create 't1', 'f1'

Which gives you a reference to the table named 't1', on which you can then
call methods.

Are yo usure your HBase is running? Can you paste the 200 last lines of
your master logs in pastebin?

Re: Getting "Table Namespace Manager not ready yet" while creating table in hbase

Hi, Praveen.

Can you share more details on HBase version?
You can look at hbase:namespace table to find out is it enabled and
deployed somewhere.
(typically you can find this on master
http://master:60010/table.jsp?name=hbase:namespace

Andrey.
