Description

Hi Anoop/Ted,
I need to delete bulk records in Hbase table based on certain criteria.
I copied one piece of code from similar thread and it throws "can not find symbol" error for most of the code.

Can you please provide me right code which would be used to delete bulk records

Here are the errors
DeleteRowsTest.java:75: error: cannot find symbol
HTable tableName = new HTable(conf, "salestoolsdata:account");
^
