The latest and greatest version of Hortonworks
HDB i.e version 18.104.22.168 addresses many of the concerns from customers/prospects who have been
considering Hortonworks HDB for their production data analytics workloads.
Below is the list of major improvements available
in Hortonworks HDB 22.214.171.124 over its predecessor.
Ranger support (in BETA mode)
Lack of support
for Ranger has been a deal breaker in field in past. Hortonworks HDB 126.96.36.199 is step in right direction and includs Beta support for Apache Ranger.
HDB 188.8.131.52 now include a RESTful service that provides integration between HDB and
Ranger policy management.
integration enables you to use Apache Ranger to authorize user access to Hortonworks
HDB resources. Using Ranger enables you to manage all of your Hadoop
components’ authorization policies using the same user interface, policy store,
and auditing stores.
ORC is a columnar
file format that provides a highly efficient way to both store and access HDFS
data. ORC files offer improvements over text and RCFile formats in terms of
both compression and performance.ORC support is
provided by a new profile “HiveORC “ exposed in the PXF Hive plug-in. The “HiveORC” profile supports access to data
stored in ORC format only through a Hive mapped table
Optimized Row Columnar file format, which had been Beta in prior versions, is now fully supported by Hortonworks HDB 184.108.40.206
Support for CentOS 7 / RHEL 7
HDB 2.2 now has downloads for Red Hat Enterprise Linux 7 and CentOS 7 operating
Compatibility with Hortonworks Data Platform ecosystem
Hortonworks HDB 2.2 is certified to work
with Hortonworks Data Platform (DHP) 2.5.3 and Ambari 2.4.2
The support for HDP 2.6 is currently
undergoing testing and is tentatively planned to be generally available in Q3
