Re: Mini Accumulo Cluster reusing the directory

I created a util for doing this, but i haven't worked on it in a while... You could see if it still works https://github.com/agwells0714/AccumuloDeveloperUtil On Wed, Sep 16, 2015 at 10:31 AM, Corey Nolet wrote: > Sven, > > What version of Accumulo are you running? We have

btw, my solution revolved around this issue: https://issues.apache.org/jira/browse/ACCUMULO-2851 which let users save their data off somewhere, then load it into the new mac cluster On Wed, Sep 16, 2015 at 10:37 AM, Andrew Wells <awe...@clearedgeit.com> wrote: > I created a util

Re: Question about best practices on column names

On the surface it adds an additional level of specification/grouping. The potential benefit we have in accumulo is that along with the fact that identical rowID's are guaranteed to be in the same file. You can use Locality Groups, to place specific Column Families into the same file as well.

Re: Change column family

to implement that iterator. looks like you will only need to override replaceColumnFamily and this looks to return the new ColumnFamily via the argument. So manipulate the Text object provided. On Wed, May 27, 2015 at 8:06 AM, Andrew Wells awe...@clearedgeit.com wrote: Looks like you want

Q4A Project

I have been working on a project, tentatively called Q4A (Query for Accumulo). Another possible name is ASQ (Accumulo Streaming Query) [discus]. This is a streaming query as the query is completed via a stream, should never group data in memory. To batch, intermediate results would be written

Re: Iterators adding data: IteratorEnvironment.registerSideChannel?

The main issue with adding data in an iterator is order. If you have can do a merge sort insertion, then you can guarantee order and its fine. But if you are inserting base on input you cannot guarantee order, and it can only be on scan iterator. On Feb 15, 2015 8:03 PM, Dylan Hutchison

I am working for a client, and they keep getting TABLET_LOAD problems. I am assuming it means that the tablet is being overloaded, but there really isn't any definition of what this means, or its cause. This also goes for other problem statuses like FiILE_READ FILE_WRITE As accumulo get bigger,
