Change subject: IMPALA-6034: Add Cpu and scanned bytes limits per query ...................................................................... IMPALA-6034: Add Cpu and scanned bytes limits per query To protect Impala from runaway queries add per query limits for Cpu and scanned bytes, limits are enforced via query options and apply to the entire query, not per backend like mem_limit. If a query exceeds any of the limits it will get cancelled. Query profile is upated to include query wide and per backend metrics for Cpu and scanned bytes. Testing: Added tests for various permutations for MAX_CPU_TIME_S and MAX_SCAN_BYTES Change-Id: I4c6015e21da684bb9f33e236d71309dd4c178a20 --- M be/src/runtime/coordinator-backend-state.cc M be/src/runtime/coordinator-backend-state.h M be/src/runtime/coordinator.cc M be/src/runtime/coordinator.h M be/src/service/impala-server.cc M be/src/service/impala-server.h M be/src/service/query-options-test.cc M be/src/service/query-options.cc M be/src/service/query-options.h M common/thrift/ImpalaInternalService.thrift M common/thrift/ImpalaService.thrift M tests/custom_cluster/test_query_expiration.py 12 files changed, 347 insertions(+), 13 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/15/10415/1 -- To view, visit http://gerrit.cloudera.org:8080/10415 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I4c6015e21da684bb9f33e236d71309dd4c178a20 Gerrit-Change-Number: 10415 Gerrit-PatchSet: 1 Gerrit-Owner: Mostafa Mokhtar <mmokh...@cloudera.com>
