-------------------------------------
Hi, [~pauloricardomg].
Thank you so much, just fixed format error and added ccm and StandaloneUpgrader
to the proposal, I didn't realize that dtest runs on ccm. I'll check them out.
Regarding {{OldFormatIterator}} and {{OldFormatDeserializer}}, I am trying to
find them on Git repository but I didn't find anything, maybe after setting up
the development environment I can decompile them. Also, can I use openJDK (7)
instead of Oracle JDK? Because I'm trying to setting up Cassandra (trunk) with
IDEA according to
[RunningCassandraInIDEA|http://wiki.apache.org/cassandra/RunningCassandraInIDEA|http://wiki.apache.org/cassandra/RunningCassandraInIDEA]
but it gives me a build failed error when I execute {{ant
generate-idea-files}}.
{code}
build-project:
[echo] apache-cassandra: /home/km/cassandra/build.xml
[javac] Compiling 45 source files to /home/km/cassandra/build/classes/thrift
[javac] javac: invalid target release: 1.8
[javac] Usage: javac <options> <source files>
[javac] use -help for a list of possible options
BUILD FAILED
/home/km/cassandra/build.xml:769: Compile failed; see the compiler error output
for details.
{code}
I'll try it again, once I have it setted up, I'll take a look along with other
materials [CASSANDRA-8888|https://issues.apache.org/jira/browse/CASSANDRA-8888]
which seems more suitable to start with.

> Labels: gsoc2016, mentor
>
> As mentioned in other places such as CASSANDRA-8047 and in the wild,
> sometimes you need to go back. A downgrade sstables utility would be nice
> for a lot of reasons and I don't know that supporting going back to the
> previous major version format would be too much code since we already support
> reading the previous version.
