Hbase tenant based data isolation

Hi All,       We are using hbase to store data on different customers. As part of design one of the key goal is to segregate data of each customers.  I came across namespace but it looks like namespace do not guarantee data segregation/isolation and i also saw the link

HTableDescriptor.hasFamily not working as expected

Hi folks, I'm new to HBase client java API and using 0.98.4-hadoop2 version. I need to check if a column family does exit even if it does not have any rows in it. The problem is that HTableDescriptor.hasFamily returns false for an empty column family so if I try to create it I will have an

Thanks Ted for your answer. This what I'm doing : catching the exception, but before I'm setting hbase.client.retries.number to 3 rather than the default value of 35 otherwise my job will hang for few minutes. Is there no other way to make the check. Best regards, On Fri, Dec 4, 2015 at 4:35

A column family is supposed to receive (some) writes. Maybe you can give us more context on why the check for column family is needed. Do you try to alter table (and adding column family) when a particular column family doesn't exist ? Cheers On Fri, Dec 4, 2015 at 7:51 AM, Mehdi Ben Haj Abbes

Re: Count rows in HBase based on partial rowkeys

Looks like the row key prefix has fixed length (40 characters). Please take a look at FuzzyRowFilter Example can be found in: hbase-server/src/test/java/org/apache/hadoop/hbase/filter/TestFuzzyRowFilter.java Cheers On Fri, Dec 4, 2015 at 1:10 PM, Arun Patel wrote:

Thanks Ted. Any easy way to this through command line? or may be through JRuby? On Fri, Dec 4, 2015 at 4:16 PM, Ted Yu wrote: > Looks like the row key prefix has fixed length (40 characters). > > Please take a look at FuzzyRowFilter > > Example can be found in: > >

can my old hbase client use new hbase version?

I want to set up a hbase cluster. I found the latest stable release is 1.1.2. But I have some old client codes writen with hbase 0.98. I don't want to rewrite them. is it possible to use 0.98 client codes to interact with 1.1.2 version server?
