Hi everybody, this discussion started in an other thread about a problem in union, but you said it was a different error then i am opening a new topic
I am doing the union of two dataset and I am getting this error Exception in thread "main" org.apache.flink.api.common.InvalidProgramException: Cannot union inputs of different types. Input1=scala.Tuple6(_1: Long, _2: String, _3: Long, _4: Long, _5: Character, _6: ObjectArrayTypeInfo<GenericType<it.polimi.genomics.core.DataTypes.GValue>>), input2=scala.Tuple6(_1: Long, _2: String, _3: Long, _4: Long, _5: Character, _6: ObjectArrayTypeInfo<GenericType<it.polimi.genomics.core.DataTypes.GValue>>) at org.apache.flink.api.java.operators.UnionOperator.<init>(UnionOperator.java:46) at org.apache.flink.api.scala.DataSet.union(DataSet.scala:1101) at it.polimi.genomics.flink.FlinkImplementation.operator.region.GenometricCover2$.apply(GenometricCover2.scala:125) ... Input1= scala.Tuple6(_1: Long, _2: String, _3: Long, _4: Long, _5: Character, _6: ObjectArrayTypeInfo<GenericType<it.polimi.genomics.core.DataTypes.GValue>>) input2= scala.Tuple6(_1: Long, _2: String, _3: Long, _4: Long, _5: Character, _6: ObjectArrayTypeInfo<GenericType<it.polimi.genomics.core.DataTypes.GValue>>) as you can see the two datasets have the same type this error only happens with a custom data type (e.g. i am using an array of GValue, an array of Int or Double works) in the last flink version it was working (milestone and snapshot) now in 0.9.0 it is not what can it be? thanks for help cheers, Michele |

Hi Michele, Thanks for reporting the problem. It seems like we changed the way we compare generic types like your GValue type. I'm debugging that now. We can get a fix in for the 0.9.1 release.On Tue, Jul 14, 2015 at 5:35 PM, Michele Bertoni <[hidden email]> wrote: Hi everybody, this discussion started in an other thread about a problem in union, but you said it was a different error then i am opening a new topic |

I was able to reproduce this problem. It turns out, this has already been fixed in the snapshot version: https://issues.apache.org/jira/browse/FLINK-2229 The fix will be included in the upcoming 0.9.1 release. Thank you again for reporting! Kind regards, Max On Wed, Jul 15, 2015 at 11:33 AM, Maximilian Michels <[hidden email]> wrote:

I think this commit fixed it in the 0.9 branch (c7e868416a5b8f61489a221ad3822dea1366d887) so it should be good in the release. On Thu, Aug 27, 2015 at 11:52 AM, Chiwan Park <[hidden email]> wrote: Hi Michele, |

Release vote just started. If everything works, the release should be out on Monday. If you like, you can use the release candidate version and contribute to the release testing. ;) Add this to your POM: <repository> <id>rc0</id> <name>Flink 0.9.1 RC0</name> </repository> Then you can use 0.9.1 as Flink version. If you do this, feel free to post to the dev list vote thread. – Ufuk On Thu, Aug 27, 2015 at 12:09 PM, Stephan Ewen <[hidden email]> wrote:
