----------------------------------------
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.
