Change subject: IMPALA-10711: Allow customizing startup's filesystem check ...................................................................... IMPALA-10711: Allow customizing startup's filesystem check At startup, Impala runs JniFrontend::checkFileSystem() to verify that it can list the root directory of the filesystem. Some deployments would like to restrict Impala to a subdirectory of the filesystem. In that circumstance, Impala may not have access to the root of the filesystem and the startup check will fail. This adds the startup parameter: startup_filesystem_check_directories to specify the directories to check in JniFrontend::checkFileSystem() at startup. For deployments that are restricted to a subdirectory, startup_filesystem_check_directories=/some/subdirectory would check /some/subdirectory rather than /. This parameter allows for a list of directories in case it is useful to verify multiple locations (such as different s3 buckets). If set to the empty string, no directories will be checked. Testing: - Added test_startup_filesystem_checks.py custom cluster test - Hand tested locally Change-Id: I68e6802424f16002c90a37b3ae2490721525e58d Reviewed-on: http://gerrit.cloudera.org:8080/17570 Reviewed-by: Csaba Ringhofer <csringho...@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> --- 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/JniFrontend.java A tests/custom_cluster/test_startup_filesystem_checks.py 5 files changed, 169 insertions(+), 6 deletions(-) Approvals: Csaba Ringhofer: Looks good to me, approved Impala Public Jenkins: Verified -- To view, visit http://gerrit.cloudera.org:8080/17570 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: merged Gerrit-Change-Id: I68e6802424f16002c90a37b3ae2490721525e58d Gerrit-Change-Number: 17570 Gerrit-PatchSet: 6 Gerrit-Owner: Joe McDonnell <joemcdonn...@cloudera.com> Gerrit-Reviewer: Csaba Ringhofer <csringho...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Joe McDonnell <joemcdonn...@cloudera.com>
