Org. Apache. hadoop. hbase. pleaseholdexception: Master is initializing

The computer re-installed the system, and set up hadoopcdh4.5 pseudo-distributed in the Ubuntu environment of the local machine. Go to hbase shell and run the following exception when creating a table:

ERROR: org.apache.hadoop.hbase.PleaseHoldException: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing    at org.apache.hadoop.hbase.master.HMaster.checkInitialized(HMaster.java:1710)    at org.apache.hadoop.hbase.master.HMaster.createTable(HMaster.java:1234)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)    at java.lang.reflect.Method.invoke(Method.java:606)    at org.apache.hadoop.hbase.ipc.WritableRpcEngine$Server.call(WritableRpcEngine.java:320)    at org.apache.hadoop.hbase.ipc.HBaseServer$Handler.run(HBaseServer.java:1428)Here is some help for this command:Create table; pass table name, a dictionary of specifications percolumn 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‘}

Finally, the IP address in the/etc/hosts file is incorrect.

#127.0.0.1 localhost
127.0.1.1 hadoop

Solution:

Modify 127.0.1.1 in/etc/hosts to 127.0.0.1, disable hbase, disable hadoop, and enable it again.
