How to create a HBase table on Kerberized Hadoop clusters

Hi SQL Data Explorers, If you are using HBase with Hue on CDH6.1.x or later, you may find Hue’s check configuration fails for HBase with following error: Failed to authenticate to HBase Thrift Server, check authentication configurations. With change from HBase(HBASE-19852), we have to configure HBase properly through Cloudera Manager with following steps to enable Hue-Hbase communication. Step 1 Navigate to CM->Clusters->HBASE-1->Configurations, search for “thrift” and verify the “Enable HBase Thrift Http Server” and “Enable HBase Thrift Proxy Users” are checked, and “Enable HBase Thrift Server Compact Protocol” and “Enable HBase Thrift Server Framed Transport” are unchecked.…

Integration with Microsoft Azure Data Lake Store Gen2

Hue continues its progress to make the Cloud platforms easier to use. We’re happy to preset compatibility with Microsoft Azure Data Lake Store Gen2 (ADLS Gen2). Hue 4.6 release brings the ability to read and write from a configured ADLS Gen2. Almost like ADLS, users can save data to ADLS Gen2 without copying or moving to HDFS. The difference between ADLS Gen1 and Gen2 is that ADLS Gen2 does not rely on the HDFS driver.…

SQL querying Apache HBase with Apache Phoenix

Apache Phoenix is a great addon to extent SQL on top of Apache HBase, the non relational distributed data store. On top of the HBase Browser, now the Editor provides a more common syntax for querying the data. Note that being a key/value store, the SQL can have different idioms, and the Editor interface still requires some polishing to fully support all the SQL UX capabilities of Hue. In this post about Phoenix, let's follow Phoenix's 15-minute tutorial then query the US_POPULATION table via the Editor:…

Additional SQL improvements: Built-in Impala language reference, Improved column samples, Dark Mode

Hi SQL enthusiasts! We've made quite some improvements to the SQL experience in Hue 4.3, in a previous post we showed some of the new exploration improvements and now we'd like to show some additional new features in the editor. After the introduction of the UDF reference panel we've received requests to also include documentation for SQL syntax. It's quite common to look at the language reference while writing certain statements and it's annoying to have to have multiple windows open.…

Accordingly to what object you are applying privileges to, you will get only the available options now. To summarize what's new, CREATE will work at the SERVER/DB scopes, while REFRESH/ALTER/DROP will work at the SERVER/DB/TABLE scopes.…

Hello Job Scheduler/Oozie users, Previously, the Hue Job browser didn’t display the Oozie workflow Graph in the Graph tab for complex Oozie workflows (when the number of nodes are more than 30 or the workflow depth is more than 24). Since Hue 4.3 and Oozie 5, Oozie provides an API to get an SVG image of the workflows. This new feature helps to display an SVG image of complex workflows in the Dasboard interface.…
