Josh Elser updated HBASE-19953: ------------------------------- Attachment: HBASE-19952.001.branch-2.patch > Avoid calling post* hook when procedure fails > --------------------------------------------- > > Key: HBASE-19953 > URL: https://issues.apache.org/jira/browse/HBASE-19953 > Project: HBase > Issue Type: Bug > Components: master, proc-v2 > Reporter: Ramesh Mani > Assignee: Josh Elser > Priority: Critical > Fix For: 2.0.0-beta-2 > > Attachments: HBASE-19952.001.branch-2.patch > > > Ramesh pointed out a case where I think we're mishandling some post\* > MasterObserver hooks. Specifically, I'm looking at the deleteNamespace. > We synchronously execute the DeleteNamespace procedure. When the user > provides a namespace that isn't empty, the procedure does a rollback (which > is just a no-op), but this doesn't propagate an exception up to the > NonceProcedureRunnable in {{HMaster#deleteNamespace}}. It took Ramesh > pointing it out a bit better to me that the code executes a bit differently > than we actually expect. > I think we need to double-check our post hooks and make sure we aren't > invoking them when the procedure actually failed. cc/ [~Apache9], [~stack]. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
