-----------------------------------------
Summary: End-to-end test framework doesn't read aggregated
counters properly
Key: IMPALA-8249
URL: https://issues.apache.org/jira/browse/IMPALA-8249
Project: IMPALA
Issue Type: Bug
Reporter: Zoltán Borók-Nagy
The test framework doesn't always read the correct value of counters from the
runtime profile. In the .test files we can have a RUNTIME_PROFILE section where
we can test our expectations against runtime profile data. We can even
calculate aggregates of runtime data, currently only SUM is supported over
integer data, e.g.:
{code:java}
---- RUNTIME_PROFILE
aggregation(SUM, RowsReturned): 2142543
{code}
However, the counters are pretty-printed in the runtime profile, which means
that if they are greater than 1000, a shortened version is printed first, then
the accurate number comes in parenthesis , e.g.:
{code:java}
RowsReturned: 2.14M (2142543){code}
When the test framework parses the value of an aggregated counter, it wrongly
tries to parse the short version as a number, which returns a wrong value (2
instead of 2142543 in the example).
