Installing the Hadoop Client
Describes how to install the Hadoop client.
Before release 6.2.0 and EEP 7.0.0, the Hadoop
client was part of the data-fabric client (the mapr-client
package).
Beginning with release 6.2.0 and EEP 7.0.0,
Hadoop and YARN services are removed from core and delivered as ecosystem components in the
EEP repository. For more information about
these services, see Installing Hadoop and YARN.
For Hadoop client-compatibility information, see Hadoop Client Compatibility.
While the mapr-hadoop-client
package is now included in the EEP repositories for RHEL, Ubuntu, and SLES, the Hadoop
client is still part of the mapr-client
zip file for Windows and Mac
platforms. Delivering Hadoop and YARN services in an
EEP makes it possible to install and upgrade the
Hadoop client package independently of the data-fabric client. You can install the Hadoop
client at the same time as the data-fabric client or later. Note that you must use
with the configure.sh
-c
option to
specify the client setup.
mapr-client
package and should be
installed after the mapr-client

client is installed with the
