If the average is around 1k per k/v entry, then I would say that 400MB/s is very good performance for incremental/streaming ingest into Accumulo on that cluster. However, I suspect that your entries are probably not that big on average. Do you have a measurement for MB/s ingest? Adam On Apr 9, 201

Pre-split as much as possible. Accumulo will take of spreading the tablets across the cluster. You have five nodes but only four tablets. This means that one node is not getting any data during the ingest process. If you can't pre-split because you don't have enough variability in the row value, an

Geoffry, Interesting you have Hadoop working in Karaf. I'm using equinox. Sure, but are we talking Karaf-specific features here? You just want a Hadoop Client bundle that works, right? The author of the Karaf-Hadoop project already worked through the classpath issues so it's not a bad starting p

Corey, Interesting you have Hadoop working in Karaf. I'm using equinox. It also sounds as if I don't need to access HFDS in order to get Accumulo to work in OSGi. If I understand you correctly, I only need have Text available. I'll look into that. It does answer my question and maybe I can avo

Geoffry, As Josh pointed out, you should only need the Hadoop libraries on the client side to use the Text object. This means you won't have to go through the pain of placing the xml files in your root bundles. Did you try the JAAS export from the packages in your container? Did that help? I agr
