Joe McDonnell resolved IMPALA-9760.
-----------------------------------
Fix Version/s: Impala 4.0
Target Version: Impala 4.0
Resolution: Fixed
It makes sense for the commit switch to GCC7 to add the compiler version to the
path. There is no need for an intermediate step with GCC 4.9.2.
> Use different locations for native toolchain packages built with different
> compilers

>
> To switch to GCC 7 with the new ABI, we want to keep the packages using the
> old ABI and new ABI separate. This means that they will need to reside in
> different directories inside IMPALA_TOOLCHAIN. There is code in other
> repositories that depends on finding things inside IMPALA_TOOLCHAIN, so it
> may be easiest to have multiple phases:
> 1. Introducing a new variable tracking the native package location which is
> the same as IMPALA_TOOLCHAIN
> 2. Switch dependent code to use this new variable
> 3. Change the value of the variable to be different for different compilers
