I have been working on a tool, that I am calling Q4A.
However, due to my upcoming wedding, I have not had much time to work on
it. I was hoping during the Accumulo Hackathon this week, I could actually

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
Andrew,
Have you considered leveraging existing SQL query layers like Hive or
Spark's SQL/DataFrames API? There are some pretty massive optimizations
involved in that API making the push-down predicates / selections pretty
easy to adapt for Accumulo.

I'm always looking for places to help out and integrate/share designs
ideas. I look forward to chatting with you about Q4A at the hackathon
tomorrow!
Have you, by chance, seen the Spark SQL adapter for the Accumulo Recipes
Event Entity Stores [1]? At the very least, it's a good example of using

This is a cool thing to work on, I hope you have great success!
A couple of questions about the motivations behind this, if you don't mind -
- There are several SQL implementations already in the Hadoop ecosystem. In
what ways do you expect this to improve upon
Thanks,
I will look into the ASL.
Thanks.

Hello everyone.
I am trying to carry out max and min kind of operations using accumulo.
But since the Accumulo iterators only operate on the entries that are
lovally hosted I get the local max and local min of the instead of a global
max and min.
To get this global max and min, I have to
No, there isn't a way to do this that doesn't involve writing it to disk.

Hi,
While connecting to accumulo through spark by making sparkRDD I am
getting the following error:
object not serializable (class: org.apache.accumulo.core.data.Key)
This is due to the 'key' class of accumulo which does not implement
serializable interface.How it can be solved and accumulo
