Automatically checking documentation and website dead links with Continuous Integration

Hi Data Crunchers, Continuous integration and automation are investment that enable a major scaling in the resource and quality of software projects. This past year saw a lot of improvements with an integrated commit flow and adding series of checks like linting of JavaScript, also running Python 3 tests automatically… This also create a virtuous circle that encourages developers to add more tests on their own (e.g. +200 since the beginning of this year), as all the plumbing is already done for them.…

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.…
