Change subject: IMPALA-7520: Fix NullPointerException in SentryProxy ...................................................................... IMPALA-7520: Fix NullPointerException in SentryProxy Prior to this patch, the code in SentryProxy could throw a NullPointerException when trying to retrieve a set of privileges for a given role name. I was able to manually reproduce the issue by doing the following steps: 1. Get all Sentry role privileges: [a, b] --> in SentryProxy 2. Add a sleep statement before getting all Sentry roles --> in SentryProxy 3. Add a new Sentry role: [c] --> Externally via Sentry CLI 4. Get all Sentry roles: [a, b, c] --> in SentryProxy Role c was added in step 3. 5. Get Sentry role privileges for role c: NPE --> in SentryProxy The fix is to add a null guard when retrieving Sentry privileges for a given role name and let the new role get updated in the next Sentry refresh. Testing: - Manually tested it by temporarily modifying the SentryProxy code and did not see the NullPointerException Change-Id: I36af840056a4d037fb5c7b1d9a167c0eb8526a11 --- M fe/src/main/java/org/apache/impala/util/SentryProxy.java 1 file changed, 5 insertions(+), 2 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/52/11552/2 -- To view, visit http://gerrit.cloudera.org:8080/11552 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I36af840056a4d037fb5c7b1d9a167c0eb8526a11 Gerrit-Change-Number: 11552 Gerrit-PatchSet: 2 Gerrit-Owner: Fredy Wijaya <fwij...@cloudera.com>
