Ariel Weisberg commented on CASSANDRA-10155:
--------------------------------------------
The fail may go deeper than just filenames.
I copied KeyCacheCQLTest from Robert's in progress work to test saving and
loading with a 2i.
I added
{code}
CacheService.instance.keyCache.submitWrite(Integer.MAX_VALUE).get();
{code}
to the end of KeyCacheCQLTest.test2iKeyCachePaths and got an exception
{code}

> 2i key cache load fails
> -----------------------
>
> Key: CASSANDRA-10155
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10155
> Project: Cassandra
> Issue Type: Bug
> Reporter: Robert Stupp
> Assignee: Ariel Weisberg
> Fix For: 2.1.9, 3.0.0 rc1, 2.2.2
>
>
> CASSANDRA-9265 changed how key cache content is serialized to disk. It uses
> {{UUID cfId}} to generate the file path for each {{ColumnFamilyStore}}.
> Since {{cfId}} of a secondary index is the same as for the base table, the
> key-cache files for 2i's and the base are the same. This will/may lead to
> deserialization failures on restart for tables with at least one 2i.
