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.…

Introducing Hue requests tracing with Opentracing and Jaeger in Kubernetes

Hue is getting easy to run with its Docker container and Kubernetes Helm package. Recent blog posts describes how to get access to logs and metrics. Even in a non distributed world it can get noisy to know how much time is being spent where in each user request. Consequently, in the context of a Data Analyst, knowing why a certain query is slow can become problematic. On top of that, adding multiple tenants and users, and more than 20 external APIs and the fog about fine grain performances appears and its becomes extremely manual and time consuming to troubleshoot.…
