IMPALA-14465: Unset HEAPCHECK when custom cluster tests restart Kudu
Custom cluster tests like TestKuduHMSIntegration restart the Kudu
service with custom startup flags. On Redhat8 ARM64, these tests
have been failing due to Kudu being unresponsive after this
restart. Debugging showed that Kudu was stuck early in startup.
This only reproduced via the custom cluster tests and never via
regular minicluster startup.
When custom cluster tests restart Kudu, the script to restart
Kudu inherits environment variables from the test runner. It
turns out that the HEAPCHECK environment variable (even when
empty) causes Kudu to get stuck during startup on Redhat8
ARM64 after the recent toolchain update.
As a short-term fix, this unsets HEAPCHECK when restarting the
Kudu service for these tests. There will need to be further
investigation / cleanup beyond this.
Testing:
- Ran the Kudu custom cluster tests on Redhat8 ARM64 and
on Ubuntu 20 x86_64
