Fix Version/s: Impala 4.2.0
Resolution: Fixed
> Bump Arrow version to 9.0.0-p2 for decimal support
> --------------------------------------------------
>
> Key: IMPALA-11709
> URL: https://issues.apache.org/jira/browse/IMPALA-11709
> Project: IMPALA
> Issue Type: Sub-task
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Major
> Fix For: Impala 4.2.0
>
>
> The current Arrow version in native-toolchain is 4.0.0 which doesn't support
> reading decimal from JSON yet. The JSON decimal support is added since
> arrow-6.0.0.
> Now the latest Arrow release is 10.0.0. However, it mandates C++ 17, which
> leads to compile errors with Impala (e.g. std::string_view undefined). So the
> highest version we can try is 9.0.0.
> We also need these two fixes:
> eec94ff40 ARROW-17847: [C++] Support unquoted decimal in JSON parser (#14242)
> 289e0c92d ARROW-17995: [C++] Fix json decimals not being rescaled based on
> the explicit schema (#14380)
> So the version is 9.0.0-p2.
