Hi Mohammad,
Our requirement is that,
Initially we have created a table 'emp' with the below detail in single
column family (cfemp )
cfemp:eno
cfemp:ename
cfemp:address
After that we have added two columns in the table ( address2, address3 and
city),
We plan to create a new coloum family called 'cfadd' to store all the
address details as below
cfemp:eno
cfemp:ename
cfadd:address -- Previously it was in cfemp column family
cfadd:address2
cfadd:address3
cfadd:city
Regards,
Ravi

Subject: Re: Changing column family in hbase
Hello Ravi,
Short answer, no. We don't have a way to achieve this. At lest I am not
aware of any. (Please share with us if you are able to achieve this.)
But, just out of curiosity, I would like to ask you, why would you want to
do that? I mean I don't see any fundamental difference between both the
schemata.
Regards,
Mohammad Tariq
