> Project: HBase
> Issue Type: Bug
> Reporter: 张双福
>
> I have a problem that I have been trap weeks, can somebody can help me?
> With full of appreciate
> The problem is below:
> I have writed about 1G data to the hbase ,then it does not work.
> when I set the hadoop dfsadmin -safemode leave ,then the hbase can use
> "list" command,but when i use "count 'tableTest' or get ,put and so on
> ,finaly ,It tell me below：
> hbase(main):002:0> count 'zsfTest'
> ERROR: org.apache.hadoop.hbase.NotServingRegionException:

> Here is some help for this command:
> Count the number of rows in a table. This operation may take a LONG
> time (Run '$HADOOP_HOME/bin/hadoop jar hbase.jar rowcount' to run a
> counting mapreduce job). Current count is shown every 1000 rows by
> default. Count interval may be optionally specified. Scan caching
> is enabled on count scans by default. Default cache size is 10 rows.
> If your rows are small in size, you may want to increase this
> parameter. Examples:
> hbase> count 't1'
> hbase> count 't1', INTERVAL => 100000
> hbase> count 't1', CACHE => 1000
> hbase> count 't1', INTERVAL => 10, CACHE => 1000
> hbase(main):003:0>
