["Ludovic Boutros (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-14055?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ludovic Boutros updated CASSANDRA-14055:
----------------------------------------
           Labels: patch  (was: )
    Fix Version/s: 3.11.x
    Reproduced In: 3.11.1, 3.10  (was: 3.10, 3.11.1)
           Status: Patch Available  (was: Open)

Here is a first little patch with a unit test and a simple fix.

I have somme issues with the unit test "SASIIndexTest.testIndexMemtableSwitching".
It works alone, but fails if the whole test is runned. 

Any help would be really appreciated.

> During index redistribution process, a new view is created.
> During this creation, old indexes should be released.
> But, new indexes are "attached" to the same SSTable as the old indexes.
> This leads to the deletion of the last SASI index file and breaks the index.
> The issue is in this function : [https://github.com/apache/cassandra/blob/9ee44db49b13d4b4c91c9d6332ce06a6e2abf944/src/java/org/apache/cassandra/index/sasi/conf/view/View.java#L62]
