Re: [geomesa-users] Accumulo Data Store has memory leak problem.
|
Hi Jim,
>Have you had a chance to test changing the library in your environment?
We have the test plan, but unfortunately hasn't do yet.
>Are you using Accumulo 1.7.2 or later with namespaces?
Yes, we are using Accumulo 1.7.2 with namespaces.
We will wait for release 1.3.1.
Thank you for reply,
Takashi

I've created a branch here: https://github.com/locationtech/geomesa/tree/scala-parsers-1.0.5. We'll get this change merged in GeoMesa 1.3.1 (which is due out within the next week).
