Michael Brown commented on IMPALA-3794: --------------------------------------- I saw this recently again. :-/ > test_breakpad.py is flaky > ------------------------- > > Key: IMPALA-3794 > URL: https://issues.apache.org/jira/browse/IMPALA-3794 > Project: IMPALA > Issue Type: Bug > Components: Infrastructure > Affects Versions: Impala 2.6.0, Impala 2.8.0, Impala 2.9.0 > Reporter: Lars Volker > Assignee: Lars Volker > Labels: breakpad, flaky > > Using the following command usually fails within an hour: {{while [ $? -eq 0 > ]; do ./run-tests.py ./custom_cluster/test_breakpad.py > --exploration_strategy=exhaustive -k test_minidump_relative_path -x -s; > done}}. The problem is, that only two of the three impalad processes will > write a minidump, while one of them won't. However in that case there is no > breakpad related error message in its logfile. > Creating the {{minidump_base_dir}} seems to alleviate the problem, suggesting > there might be a race condition somewhere in the call to > {{boost::filesystem::create_directories}}. > This problem only seems to arise in the specific scenario of multiple impalad > processes sharing the same {{minidump_base_dir}} which also has to be > non-existent. Outside of tests it seems like it cannot occur. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
