If the Impala version is set to a release build as described in point 8 in the
"How to Release" document
([https://cwiki.apache.org/confluence/display/IMPALA/How+to+Release#HowtoRelease-HowtoVoteonaReleaseCandidate),]
TestIcebergTable.test_compute_stats fails:

The problem is the file size which is 2.32KB instead of 2.33KB. This is because
the version is written into the file, and "x.y.z-RELEASE" is one byte shorter
than "x.y.z-SNAPSHOT". The size of the file in this test is on the boundary
between 2.32KB and 2.33KB, so this one byte can change the value.
We could use a row_regex to accept both values so it works for both snapshot
and release versions.
