I couldn't find an answer to this; though it's hard to think it hasn't been asked before. If I have a very large batch get pulled into spark streaming (I know, that's bad in a perfect world), then spark still keeps scheduling a new batch every 15 seconds. Eventually, I can end up with like 500 "pending" batches. Is there a way to tell it… Show more
Hello, I am currently looking into installing the MAPR version of Hue on RedHat 7. After going over the documentation, it seems the typical method is to simply use yum. However, my yum repository did not find the package Is it possible to either add the correct repository to yum, or to install without yum (such as wget)? Thank you

How to mount MapR-FS with NFS on Windows using AD authentication and respect POSIX/ACE user rights ?
Hello, We are having a MapR cluster running, which is using Active Directory (AD) for authentication, and user rights management using POSIX and ACE depending on the use cases.

Hi, I already solve this last night. It seems like that you need to run the script using the MapR admin (not the root/other user) in able to set the permissions.

So, I've got some a database in the MSSQL 2016 server. What is the best possible way to move the data to MapR and do my analysis?
Hi, Just a couple of comments. You don't have to bring the data over and import it in to JSON docs. JSON is just one way to represent the data as a hierarchical model. The issue is that Big Data isn't really relational. There's a cost when it comes to joining relational tables where you're providing data in a record format. So you can…
WHAT are some current tips & best practices for performing on-the-fly validation (and handling of data deemed "invalid") when using ImportTsv to bulk-load data into tables? MULTIPLE passes of ImportTsv would be expected, but does this mean the table has to stay in "import" mode until all the incoming data is deemed "valid" and permitted to be… Show more
Hi, Here's something to think about. What's invalid data? While this may seem simple, its not. MapRDB is schema-less. So you have explain what's makes an input record invalid. So... if you want to load data from a source in to MapRDB and you want to validate it on the fly, you would need to do either a M/R or Spark job to either process…
