Fellas, I have noticed a weird thing while working on upgrading Ignite in Zeppelin. One of the tests failed because of
Caused by: class org.apache.ignite.spi.IgniteSpiException: Local node's marshaller differs from remote node's marshaller (to make sure all nodes in topology have identical marshaller, configure marshaller explicitly in configuration) [locMarshaller=org.apache.ignite.marshaller.optimized.OptimizedMarshaller, rmtMarshaller=org.apache.ignite.internal.binary.BinaryMarshaller, locNodeAddrs=[testing-worker-linux-docker-a1225458-3234-linux-7.prod.travis-ci.org/0:0:0:0:0:0:0:1%1, /127.0.0.1, /172.17.12.239], locPort=0, rmtNodeAddr=[testing-worker-linux-docker-a1225458-3234-linux-7.prod.travis-ci.org/0:0:0:0:0:0:0:1%1, /127.0.0.1, /172.17.12.239], locNodeId=8fa598a2-9986-4f29-ba8d-8f857048e227, rmtNodeId=3aa33408-afea-48c7-941c-8ea87429f44d] At the glance, it seems like running nodes in server and client modes somehow trigger different defaults for the marshallers, but I wasn't able to quickly find anything in the code proving my point. I've ended up forcing OptimizedMarshaller for the server node in the Zep's ignite/src/test/java/org/apache/zeppelin/ignite/IgniteSqlInterpreterTest.java and it solved the immediate issue. However, the situation seems worthy noting on dev@ Cheers, Cos
