[jira] [Commented] (CASSANDRA-20402) Create new RequestFailureReason - INDEX_BUILDING and return it to end users while an index is building

    [ https://issues.apache.org/jira/browse/CASSANDRA-20402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17940158#comment-17940158 ]

-------------------------------------------------

With the last change https://github.com/apache/cassandra/pull/3955/files#diff-5cddfa459aa739fe34f47d3a810b0f88168b84a7510d6428abc9b60c6a649a32R851
_secondary_indexes_test.py::TestSecondaryIndexes::test_failing_manual_rebuild_index_ was failing that the index is not available. 
That seems like a regression to me. Originally, I made that change because _testReadOnlyIndex_ and _testWriteOnlyIndex_ were failing, and it seemed like a miss that _markIndexFailed_ was not marking the index as failed but reading through CASSANDRA-13606; this may have been intentional?
In that sense, I guess the right fix for _testWriteOnlyInde_x and _testReadOnlyIndex_ is to change the type of exception - _IndexBuildInProgressException_. So I'd say changing _testReadOnlyIndex_ and _testWriteOnlyIndex_ exceptions is probably the right way to fix this. [~maedhroz], what do you think?

> Currently, we return INDEX NOT AVAILABLE to the users while an index is building, which makes it unclear to users whether the index is building or there is an issue.
> Differentiate the two cases by adding INDEX_BUILDING.
