Hi,
I have a HBase table which is populated from pig using PigStorage.
While inserting, suppose for rowkey i have a duplicate value.
Is there a way to prevent an update?.
I want to maintain the version history for my values which are unique.

Hi Krishna,
HBase will store them in the same row, same cell but you will have 2
versions. If you want to keep just one, setup the version=1 on the table
side and only one will be stored. Is that what yo mean?

If i put the same value in my table for a particular column for a rowkey i
want HBase reject this value and retain old value with old time stamp.
In other words update only when value changes.

You can do check and puts to validate if value is already there, but it's
slower...

You should create your own proto file and compile that with the Google
Protocol Buffer compiler. Take a look at the SingleColumnValueFilter's
code:

I was under impression, probably mistakingly, that as of 0.96 placing
the filter on hdfs under hbase lib directory is sufficient and RS should
load the filter dynamically from hdfs. Is that not the case?

I haven't tried dynamic loading of filters on RS, but I know it does exist.
See https://issues.apache.org/jira/browse/HBASE-9301.
If you still can't get it to work, then I suggest distributing your filters
to the RS and restart them. Let us know how everything works out.

Also, if you do end up using dynamic loading, you'll need a way to version
your filters because the RS will not reload a JAR if it changes.
