Hi,
I am trying to import an accumulo table from an HDFS directory. However
when i use the importtable function in the java API I get the following
error:
org.apache.accumulo.core.client.AccumuloException: Table import directory
/backup/Data_records does not exist!
I have verified that this
Hi,
I have a use case where I need to send out notifications based on changes in a
table. Are there any kind of listeners which can be used to listen to a change
in table event in accumulo?
How do I go about this use case?
Thanks
Vaibhav
I think neither of these would contribute much to load balancing. HDFS
replication is mostly a safeguard against Single Points of failure in a
Hadoop cluster. However, Data center replication would ensure the
availability of an Accumulo instance.

Creating an Inverted Index could serve your use case. You can store the
column family and column qualifier both in the row of the index table
separated by a delimiter.
For eg cf|cq
And then perform queries on just the row id to get a low query time.

Dear all,
I'm trying to visualize accumulo metrics on a Kibana dashboard so that
analysis can be performed on them. For that I need to index the individual
metrics in an elastic-search index. Can you please tell me how can I get
these metrics through java code/api? If not through the public api
Hi Denis,
As far as my experience with working on accumulo, ideally you should use
the client libraries corresponding to your server version. But I have also
used the 1.7.0 libraries on my 1.6.3 accumulo cluster without ever facing a
problem.

Hello everyone,
I was wondering why did the developers chose java for writing accumulo.
What advantage it has over using any other language say C++(in which
another popular nosql database MongoDB is written) in context of accumulo?
Thanks
Vaibhav
that do not need to be
high performance in Java, like tablet assignment and management of cluster
state is nice.

Dear all,
I have the following questions on intersecting iterator and partition ids
used in document sharded indexing:
1. Can we run a boolean and query using the current intersecting iterator
on a given range of ids. These ids are a subset of the total ids stored in
the column qualifier field
Hi everyone,
I wanted to ask if Accumulo supports connection pooling?
If yes is there something in the JAVA api that can be used to make use of
it?
Thanks

queries go to one tablet, and 90% go to the
other.

. Your best approach is probably to create an index table on
whatever you are originally trying to query (assuming those 1 ids came
from some other query).

One thing I would like to know. Does pre-splitting the data play a part
in querying accumulo?
Because I managed to somewhat decrease the querying time.

Hi,
I am using BatchScanner to scan rows from a accumulo table. The table has
around 187m entries and I am using a 3 node cluster which has accumulo
1.6.1.
I have passed 1 ids which are stored as row id in my table as a list in
the setRanges() method.
This whole process takes around 50
threads if your hardware can support them. The worst
that'll happen is the client program crashes during testing. If that
happens, cut the number of threads in half. And so on.

It would be awesome to watch all the talks at the summit.

Hi josh,
We solved it using the kryo serializer library to serialise the key class.

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

I also had this query that might be similar to shweta.
What I want to do is process the key value pairs that I get from

Currently I was writing these values to tables from inside the iterators,
but I read in the new

In general, start small and get a nice, tested codebase. That will help in
