In Sentry 1.5.1, BitFieldAction is an abstract class: https://github.com/apache/sentry/blob/release-1.5.1/sentry-core/sentry-core-common/src/main/java/org/apache/sentry/core/common/BitFieldAction.java#L22. Sentry removed the abstract requirement in Sentry 2.0.0: https://github.com/apache/sentry/blob/master/sentry-core/sentry-core-common/src/main/java/org/apache/sentry/core/common/BitFieldAction.java#L23
To support both versions of Sentry, we need to fix https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/authorization/Privilege.java#L72 . *Fredy Wijaya* | Software Engineer e. fwij...@cloudera.com cloudera.com <https://www.cloudera.com> [image: Cloudera] <https://www.cloudera.com/> [image: Cloudera on Twitter] <https://twitter.com/cloudera> [image: Cloudera on Facebook] <https://www.facebook.com/cloudera> [image: Cloudera on LinkedIn] <https://www.linkedin.com/company/cloudera> ------------------------------ On Mon, Apr 16, 2018 at 5:10 PM, Sailesh Mukil <sail...@cloudera.com> wrote: > I get this error when trying to the build the Impala frontend.
