Change subject: IMPALA-7599: make the number of local cache retries configurable ...................................................................... IMPALA-7599: make the number of local cache retries configurable Under heavy read/write load, the number of retries needed for queries in order to skip over inconsistent metadata exceptions needs to be set higher. This change makes the number of retries configurable. It can be set with the newly added flag --local_catalog_max_retries. In addition, this change increases the default from 10 to 40, which was sufficient when handling several workloads with high read/write load. Made several fixes to exception messages. Testing: - manual tests - added an e2e test that sets the flag and checks for inconsistent metadata Change-Id: I4f14d5a8728f3cb07c7710589c44c2cd52478ba8 --- M be/src/runtime/exec-env.cc M be/src/util/backend-gflag-util.cc M common/thrift/BackendGflags.thrift M fe/src/main/java/org/apache/impala/service/BackendConfig.java M fe/src/main/java/org/apache/impala/service/Frontend.java M tests/common/impala_test_suite.py M tests/custom_cluster/test_local_catalog.py 7 files changed, 66 insertions(+), 1 deletion(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/39/11539/1 -- To view, visit http://gerrit.cloudera.org:8080/11539 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I4f14d5a8728f3cb07c7710589c44c2cd52478ba8 Gerrit-Change-Number: 11539 Gerrit-PatchSet: 1 Gerrit-Owner: Vuk Ercegovac <[email protected]>
