MapR 6.0 Documentation

6.0 Development
This section contains information related to application development for ecosystem components and MapR products including MapR-DB (binary and JSON), MapR-FS, and MapR Streams.
- Application Development Process
  Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will be accessed.
- MapR-FS and Apps
  The following sections provide information about accessing MapR-FS with C and Java applications.
- MapR-DB and Apps
  This section contains information about developing client applications for JSON and binary tables.
- MapR-ES and Apps
  MapR-ES brings integrated publish and subscribe messaging to the MapR Converged Data Platform.
- MapReduce and Apps
  This section contains information associated with developing YARN applications.
- MapR Data Science Refinery
  The MapR Data Science Refinery is an easy-to-deploy and scalable data science toolkit with native access to all platform assets and superior out-of-the-box security.
- MapR Data Fabric for Kubernetes FlexVolume Driver
  This section describes how to use and troubleshoot the MapR Data Fabric for Kubernetes FlexVolume Driver.
- Ecosystem Components
  The following sections provide information about each open source project that MapR supports.
  - MapR Ecosystem Packs
    A MapR Ecosystem Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions. Only one version of each ecosystem component is available in each MEP. For example, only one version of Hive and one version of Spark is supported in a MEP.

Configure LDAP Authentication Between Hue and Hive

About this task

You can configure Hue to use LDAP Authentication when it communicates with HiveServer2. Before you configure Hue to use LDAP authentication with HiveServer2, verify that HiveServer2 is configured to use LDAP authentication. For more information, see Configure HiveServer2 to use LDAP Authentication with OpenLDAP.

Complete the following steps to configure LDAP authentication between Hue and Hive:

Procedure

Configure Hue to connect to Hive with LDAP authentication:

Configure the [beeswax] section of the hue.ini: set mechanism option.
For Hue 3.10 or later, set the auth_username and auth_password options in the [desktop] or [beeswax] sections of hue.ini; for Hue 3.9, set the ldap_username and ldap_password options in the [desktop] section.

The following examples summarize these changes:

Example for Hue 3.10

[desktop]
  ...
  # Default LDAP/PAM/.. username and password of the hue user used for authentications with other services.
  # e.g. LDAP pass-through authentication for HiveServer2 or Impala. Apps can override them individually.
  auth_username=sampleuser
  auth_password=123456
  ...
[beeswax]
  ...
  # Security mechanism of authentication none/GSSAPI/MAPR-SECURITY
  mechanism=LDAP

Example for Hue 3.9

[desktop]
  ...
  # LDAP username and password of the hue user used for LDAP authentications.
  # Set it to use LDAP Authentication with HiveServer2 and Impala.
  ldap_username=sampleuser
  ldap_password=123456
  ...
[beeswax]
  ...
  # Security mechanism of authentication none/GSSAPI/MAPR-SECURITY
  mechanism=LDAP

Optional: Configure Hue to authenticate users through LDAP. See Configure Hue with LDAP.

Restart Hue:

maprcli node services -name hue -action restart -nodes <space delimited list of nodes>
