Batch and checkAndPut

I saw a similar question but not exactly what I have.I have a row with
several fields. I would like to update these fields for one row in a batch
(i assume it will be atomic) but I would like to update them if one of these
fields value satisfy a condition. What are my options? Thanks, Victor

Re: Batch and checkAndPut

You can use HTable.checkAndPut():

  boolean checkAndPut(byte[] row, byte[] family, byte[] qualifier,

      byte[] value, Put put) throws IOException;
Take a look at its javadoc for details.

Cheers
