Historically, the Impala documentation has lived on the Cloudera web site. For reference until we disentangle the Impala docs from the CDH-specific ones, here is a link to the Impala doc starting page on cloudera.com.
Most Impala-related subjects are covered underneath that starting page - you can see them by expanding the "Impala" branch of the navigation tree on the left.
A few Impala-related topics are scattered elsewhere throughout the Cloudera docs. These tend to have more CDH and Cloudera Manager dependencies and will probably require more work to disentangle:
...
- Authentication with Kerberos and LDAP should be fairly generic.
- Authorization with Sentry relies on another Apache project and should have relatively few CDH dependencies.
- Auditing is related to Cloudera Navigator. We can document the "hooks" in the Apache context, but the usage instructions for auditing are probably tool-specific.

; however, the entire rendered Impala documentation set is now available on the Documentation tab of the Apache Impala (incubating) web site. The rendered documentation is available in HTML and PDF. These links include all of the currently available Impala documentation: the release notes, SQL reference, installation, administration, and development guides.
Authoring Logistics
Source of the main Impala documentation (SQL Reference and such) is in XML, using the DITA XML format and buildable by an open source toolchain.
