- 9. The MapR Client
A MapR distribution of the
Hadoop shell
A tool to submit jobs to the
cluster from your workstation
Compatible with:
– Windows
– Mac
– Linux
Permissions/Credentials the
same as the cluster
Work with the cluster from your laptop

Drag and drop
Open files and apps
Watch live data come in
Fully read/write
Multiple concurrent reads/writes
Easy to get data in/out
Same namespace paths as Hadoop
Mount with
-o tcp,ver=3,nolock
