hbase遇到的一些问题

目录

ERROR： org.apache.hadoop.hbase.ipc.ServerRunningYetException: Server is not running yet 

ERROR：Cant't get master address from Zookeeper; znode data == null

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

---

ERROR： org.apache.hadoop.hbase.ipc.ServerRunningYetException: Server is not running yet 

hbase保存， 压缩引起的

解决办法：

查看dfs模式，果然是安全模式

grid@master1:~$ hadoop dfsadmin -safemode get 
Safe mode is ON

关闭dfs安全模式

grid@master1:~$ hadoop dfsadmin -safemode leave

Safe mode is OFF

再次启动Hbase，能正常启动

:::::::::

ERROR：Cant't get master address from Zookeeper; znode data == null

hbase没有master节点：

  重启hbase

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:


  hbase> list
  hbase> list 'abc.*'
  hbase> list 'ns:abc.*'
  hbase> list 'ns:.*'

查看一下mater节点的日志发现

 

最后定位到是在hbase-site.xml加了一个配置

<property>
     <name>hbase.hstore.engine.class</name>
     <value>org.apache.hadoop.hbase.regionserver.DateTieredStoreEngine</value>
</property>

因为这个配置报错了， 在当前的hbase版本不存在这个类。

把这个配置删掉后，在重新就成功了， 差不多弄了2天，最后才定位到这里，我也是醉了。

注意：出现上面问题org.apache.hadoop.hbase.PleaseHoldException: Master is initializing的原因有很多

      解决问题最好的办法： 就是去看log的报错原因，然后再去百度，谷歌。

      在出现这个错误的时候，执行list后，一定要查看log上的报错，查询报错的原因，千万不要报错了就去百度。

      你在网上一搜，别人都是把解决方法写下来，但是错误原因没有，然后很浪费你的时间，之前我就是这样浪费了很多时间，而且最后也没解决问题。
