各種配置之後,出現的錯誤具體為：

進去 hbase shell 之後，出現：

hbase(main):003:0> create 'student','Sname','Ssex','Sage','Sdept','course'

ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing
    at org.apache.hadoop.hbase.master.HMaster.checkInitialized(HMaster.java:2808)

For usage try 'help "create"'

其根源在於 ./hdfs dfs -rm -r /hbase 這句話:

清除/hbase檔案系統:

hadoop@jac:~/Desktop$ stop-hbase.sh
stopping hbase....
 

hadoop@jac:/usr/local/hadoop/bin$ ./hdfs dfs -rm -r /hbase
Deleted /hbase
hadoop@jac:/usr/local/hadoop/bin$ start-hbase.sh

hadoop@jac:/usr/local/hadoop/bin$ hbase shell

這樣子純粹做了一遍之後，確實好了

hbase(main):001:0> create 'student','Sname','Ssex','Sage','Sdept','course'
Created table student
Took 1.6930 seconds                                                                  
=> Hbase::Table - student
hbase(main):002:0>
