If you can avoid it, don't install or run another Hadoop on your system. This is an easy source of problems when developing as out-of-date binaries, headers and configuration files can get silently picked up.

Mirror upstream JIRA to downstream

We track all upstream P1 and P2 issues in our downstream Jira. Replication happens automatically, but can also be done by running the jira-mirror Jenkins job. To trigger this job you can use this bookmarklet on any public JIRA page:

 javascript:location.href='http://golden.jenkins.cloudera.com/view/Impala/job/jira-mirror/parambuild/?UPSTREAM_ISSUE='+document.location.href;

Navigate from upstream JIRA to downstream

Often you find yourself navigating between upstream and downstream JIRA pages related to the same issue. All downstream JIRAs should have a link to the upstream JIRA. To find the corresponding downstream JIRA from an upstream page, you can use this bookmarklet:

javascript:location.href='https://jira.cloudera.com/issues/?jql=text%20~%20%22'+document.location["pathname"].split('/')[2]+'%22';

It works on pages like https://issues.cloudera.org/browse/IMPALA-3641.

Navigate to latest version of docs

Google search will often send you to documentation of older releases. To navigate to the latest version of a documentation page, you can use this bookmarklet:

javascript:location.href='http://www.cloudera.com/documentation/enterprise/latest/topics/' + document.location["pathname"].substring(document.location["pathname"].lastIndexOf('/') + 1);

It works on pages like https://www.cloudera.com/documentation/enterprise/5-8-x/topics/impala_parquet.html.
