Hue 3.11 with HDP 2.5

Image
By
Listen:

Works fine with CentOS / RHEL, I used 6.8 in that case. Epel has to be available, if not, install the repo.
And I ask me why Hortonworks didn't integrated Hue v3 in their HDP release - I mean, Hue v2 is older as old and lacks dramatically on functionality.
Anyhow, lets get to work.

sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

sudo yum install ant gcc krb5-devel mysql mysql-devel openssl-devel cyrus-sasl-devel cyrus-sasl-gssapi sqlite-devel libtidy libxml2-devel libxslt-devel openldap-devel python-devel python-simplejson python-setuptools rsync gcc-c++ saslwrapper-devel libffi-devel gmp-devel apache-maven

sudo mkdir /software; sudo chown hue: /software && cd /software
wget https://github.com/cloudera/hue/archive/master.zip -O hue.zip && unzip hue.zip; cd hue-master; sudo mkdir -p /usr/local/hue && chown -R hue: /usr/local/hue && make install

HDP config changes:

Oozie => Custom oozie-site
oozie.service.ProxyUserService.proxyuser.hue.groups *
oozie.service.ProxyUserService.proxyuser.hue.hosts *

Hive => Custom webhcat-site
webhcat.proxyuser.hue.host *
webhcat.proxyuser.hue.groups *

HDFS => Custom core-site
hadoop.proxyuser.hue.hosts *
hadoop.proxyuser.hue.groups *

At the end, hue.ini needs to be configured to fit the installation, here's an example - I use 8899 as HueUI port:

http_port=8899
app_blacklist=impala,security
hive_server_host=hue3.azure.intern
hbase_clusters=(Cluster|hue3.azure.intern:9090)
solr_url=http://hue3.azure.intern:8983/solr/

At least a new security rule for port 8899 has to be created, as well as the hbase thrift service has to be started per:
nohup hbase thrift start &

Configure Hue:
/usr/local/hue/build/env/bin/hue syncdb
/usr/local/hue/build/env/bin/hue migrate

Start Hue:
/usr/local/hue/build/env/bin/supervisor -d

Login per http://your_hue3_host:8899

I strongly recommend to use MySQL as an backend DB, but for first test the integrated SQLite instance is fine, too.


Issues:
HUE-4701 - recreate the saved queries from sample notebook

Why Is Customer Obsession Disappearing?

By
 It's wild that even with all the cool tech we've got these days, like AI solving complex equations and doing business across time zones in a flash, so many companies are still struggling with the basics: taking care of their customers.The drama around Coinbase's customer support is a prime example of even tech giants messing up. And it's not just Coinbase — it's a big-picture issue for the whole industry. At some point, the idea of "customer obsession" got replaced with "customer automation," and now we're seeing the problems that came with it. "Cases" What Not to Do Coinbase, as main example, has long been synonymous with making cryptocurrency accessible. Whether you’re a first-time buyer or a seasoned trader, their platform was once the gold standard for user experience. But lately, their customer support practices have been making headlines for all the wrong reasons: Coinbase - Stuck in the Loop:  Users have reported being caugh...

MySQL Scaling in 2024

By
When your MySQL database reaches its performance limits, vertical scaling through hardware upgrades provides a temporary solution. Long-term growth, though, requires a more comprehensive approach. This involves optimizing the database strategically and integrating complementary technologies. Caching The implementation of a caching layer, such as Memcached or Redis , can result in a notable reduction in the load and an increase ni performance at MySQL. In-memory stores cache data that is accessed frequently, enabling near-instantaneous responses and freeing the database for other tasks. For applications with heavy read traffic on relatively static data (e.g. product catalogues, user profiles), caching represents a low-effort, high-impact solution. Consider a online shop product catalogue with thousands of items. With each visit to the website, the application queries the database in order to retrieve product details. By using caching, the retrieved details can be stored in Memcached (a...

What the Heck is Superposition and Entanglement?

By
If you’ve ever heard the words superposition or entanglement thrown around in conversations about quantum physics, you may have nodded politely while your brain quietly filed them away in the "too confusing to deal with" folder.  These aren't just theoretical quirks; they're the foundation of mind-bending tech like Google's latest quantum chip, the Willow with its 105 qubits. Superposition challenges our understanding of reality, suggesting that particles don't have definite states until observed. This principle is crucial in quantum technologies, enabling phenomena like quantum computing and quantum cryptography. What's in for us? Short, nothing at the moment. 105 qubits sounds awesome, but it would neither crack encryption nor enhance AI in the next few years. There are some use cases for Willow, like drug (protein) discovery or solving certain mathematical problems when they aren't too complicated. Right now, Google managed to turn physical qubits ...
