Erroneous SwapFree on LXC causes problems with CDH install

Read Original

The article details troubleshooting a CDH 5.7 installation failure on Linux Containers (LXC) under Proxmox. The YARN service failed due to a NumberFormatException when parsing an impossibly large SwapFree value (18446744073709550384 kB) from /proc/meminfo. The root cause was configuring the LXC container with zero swap. The solution involved setting a small swap space (512MB) via the Proxmox CLI, which corrected the /proc/meminfo output and allowed the CDH cluster setup to complete successfully.
