    <p>I am getting some issues in HBase. When I try to start hadoop , it starts without any issue.but HBase not works.DataNode , HRegionServer , secondaryNameNode etc all are working but HMaster is not running, when I start hbase.Sometimes it throws an exception "RegionServer is running as process #xyz .stop it first.Another strange thing is HBase logs are printing "Matser started" but when we check , it is not start.I am searching out the issue , but unable to understand. Guide me if you get a clue.Here the logs of HBase given below</p> <pre><code>Wed Apr 4 17:48:46 PKT 2012 Starting master on hbase ulimit -n 1024 2012-04-04 17:48:48,804 INFO

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
