             Summary: Delete from table more than 100 rows fails with IndexOutOfBould
                 Key: PHOENIX-3969
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3969
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.11.0
            Reporter: Sergey Soldatov
            Assignee: Sergey Soldatov
            Priority: Critical


That happens because in UngroupedAggregateRegionObserver to check whether we have something to commit we call readyToCommit. We do that for both - data table mutations and local indexes ( indexMutations). In this method we check only rows count from original table, but not the size of mutations list. Since indexMutations is using only for local indexes, in regular cases the list will be empty and when we call commitBatch for empty list it fails with an exception :
