Is there a parameter that we can setup in MapR? Monitoring cluster 24*7 and killing manually is lot of effort. Apparently the users are claiming that this possible in Horton works using
We're in the process of migrating a legacy batch-based system (Spark) to a streaming system (also Spark). The old system digests very large data files to a columnar database using Sqoop. The new system should digest the same data to OpenTSDB over MapR-DB. We need to shut down our legacy database and replace it with OpenTSDB as our first
I am about to take the MCSD certification tomorrow and I was able to access all the relevant courses just fine up until the recent split into Essential and Pro. I was told that since I am already enrolled in those courses, I should still be able to access them. I am able to access everything I enrolled into except lesson 2 & 3 of DEV 360.
I went to go try playing with with librdkafka to use streams today. My goal was to get something that used librdkafka working with the MapR librdkafka. While I am not good at any of this stuff, I did once stay at a Holiday Inn Express. In summary, I found that I MapR likely used version 0.9.1 as a starting base for their

Hi this is currently my setup, having a 2 node cluster bare metal servers. We started 2 node in order to perform the adding a new node to the cluster resulting to a three node cluster. But before doing that we need to have a healthy 2 node cluster. Unfortunately hivemeta service is producing down alarm. Here are the specs of two
Hey, We're building a system using OpenTSDB on top of MapR-DB and it is working quite well. Before getting too invested though, we wanted to understand our options. We're keen to use MapR-DB for its speed and simplicity. We're also pretty excited about Apache Phoenix (it would make the target system much more powerful
