Hi, all I’m trying the JDBC server, so the cluster is running the version compiled from branch-0.1-jdbc
Unfortunately (and as expected), it cannot run the programs compiled with the dependency on spark 1.0 (i.e. download from maven) 1. The first error I met is the different SerializationVersionUID in ExecuterStatus I resolved by explicitly declare SerializationVersionUID in ExecuterStatus.scala and recompile branch-0.1-jdbc 2. Then I start the program compiled with spark-1.0, what I met is 14/07/13 05:08:11 WARN AppClient$ClientActor: Could not connect to akka.tcp://sparkMaster@172.31.*.*:*: java.util.NoSuchElementException: key not found: 6 14/07/13 05:08:11 WARN AppClient$ClientActor: Connection to akka.tcp://sparkMaster@172.31.*.*:* failed; waiting for master to reconnect... I don’t understand how "key not found: 6” comes Also I tried to start JDBC server with spark-1.0 cluster, after resolving different SerializationVersionUID, what I met is that when I use beeline to run “show tables;”, it shows some executors get lost and tasks failed for unknown reason Anyone can give some suggestions on how to make spark-1.0 cluster work with JDBC? (maybe I need to have a internal maven repo and change all spark dependency to that?) Best, -- Nan Zhu
