Subject [jira] [Updated] (HBASE-12617) Running IntegrationTestBigLinkedList against cluster getting not an instance of org.apache.hadoop.hbase.MiniHBaseCluster
Date Wed, 03 Dec 2014 00:28:12 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12617?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-12617:
--------------------------
    Attachment: 12617.txt

Simple patch. Remove the safeguard check for minihbasecluster when getting a connection. 
Let it just hang in here if you call getConnection when no cluster.  Lets see what hadoopqa
thinks.  This change makes my IT test against a cluster work again.

> We used to create an HBaseAdmin internally with  managed connection but we changed it
to use the HTU's admin.  In the patch we added check that there is a HTU cluster up and running
-- a mini cluster -- but there won't be in the case of an IT test going against a cluster.
