New in This Release

  • The Hue package no longer includes the Simba Drill JDBC driver and instead includes the Drill JDBC driver from the mapr-drill-internal package (MHUE-383). To connect to Drill using the Drill JDBC Interpreter you need to have the mapr-drill-internal package installed on the node with the Hue server.
  • The Drill ODBC interpreter is optionally available in Hue through the SQLAlchemy interface. It requires the Simba Drill ODBC drivers installed on the system and available only on RedHat/CentOS (MHUE-327).
  • Environment configuration files for Hue server should now be configured in the ${HUE_HOME}/desktop/conf/env.d directory instead of ${HUE_HOME}/bin/env.d.
  • Hue now has the following HTTP security headers configured by default (MAPR-CORE-307):
    • X-Content-Type-Options
    • X-XSS-Protection
    • Strict-Transport-Security
    • Content-Security-Policy
  • TLSv1 and TLSv1.1 were disabled (MHUE-328)
  • In kerberized environments, the Hue kt_renewer process is started automatically with Hue server (MHUE-387).
    Note: In Hue 4.3.0-1912, support for the integration of Drill with the Table Browser in Hue was added as an experimental feature.

Known Issues and Limitations

  • MapR does not support the integration between Hue 4.6.0 and the following components:
    • Solr Search
    • ZooKeeper
  • Integration between Hue 4.6.0 and Sentry 1.7 is supported on secure clusters that use Kerberos authentication, but it is not supported on secure clusters that use MapR-SASL authentication.
  • MHUE-209 Hue cannot create a table from *.csv file via importer from ADLS.
  • Hue uses python parquet lib to read parquet files. This library does not support all possible parquet formats.
  • When the [notebook] section of the hue.ini contains a Drill entry that precedes the Hive entry, the Table Browser uses the Drill back end. This can be turned off by changing the force_hs2_metadata=true setting in the [metastore] section of the hue.ini file.
