             Summary: CDC doesn't work if the "Cache objects transformation" is applied
                 Key: IGNITE-20528
                 URL: https://issues.apache.org/jira/browse/IGNITE-20528
             Project: Ignite
          Issue Type: Bug
            Reporter: Sergey Korotkov


CDC doesn't work If some cache objects transformation is applied (see the [https://cwiki.apache.org/confluence/display/IGNITE/IEP-97+Cache+objects+transformation).|https://cwiki.apache.org/confluence/display/IGNITE/IEP-97+Cache+objects+transformation)]

ignite_cdc.sh utility produces the NPE (see below). The immediate reason of the NPE is that ignite_cdc.sh uses the reduced version of the context (StandaloneGridKernalContext), which doesn't contain the GridCacheProcessor.
