當我們進入到 HBase shell 後，使用 “status” 命令檢視 HBase 執行狀態時，出現以下報錯資訊：

hbase(main):001:0> status

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

Here is some help for this command:
Show cluster status. Can be 'summary', 'simple', 'detailed', or 'replication'. The
default is 'summary'. Examples:

  hbase> status
  hbase> status 'simple'
 

  hbase> status 'summary'
  hbase> status 'detailed'
  hbase> status 'replication'
  hbase> status 'replication', 'source'
  hbase> status 'replication', 'sink'

這裡提供一個可能的原因：幾臺主機的當前時間相差大於30秒
