Jim Brennan commented on HDFS-15971:
------------------------------------
[~gautham], [~elgoiri], [~ebadger] There still seems to be a problem here.
Our development systems are RHEL7 with GCC 4.8.5. Until this jira went in, I
had no problems building native code on that system. And we don't use docker
for our builds. If I revert this change, I can build with no problems.
It looks like HDFS-15740 caused a need for the rhel8 build instructions to be
updated to change:
{noformat}
CMake 3.1 --> CMake 3.19
GCC 4.8.1 or later --> GCC 9.3.0 or later
{noformat}
The Cmake update seems reasonable, but do these changes really justify updating
the GCC from 4.8 to 9.3 - that's a pretty significant change. I don't think
we usually upgrade dependencies that aggressively.
But my build was still working fine before this jira went in. Apparently
previous changes did not require these upgrades for all platforms.
[~elgoiri] mentioned fuse dependencies. Does this change require Linux FUSE?
I think that used to be optional.
