Hi, I have some json files that I want to transform to parquet.
We have been doing this without any issues but this time around I get this exception: Error: SYSTEM ERROR: IllegalStateException: Failure while reading vector. Expected vector class of org.apache.drill.exec.vector.NullableVarCharVector but was holding vector class org.apache.drill.exec.vector.complex.MapVector. Fragment 2:0 [Error Id: 86501e92-5319-4540-9cf3-9a1aede4554b on localhost:31010] (state=,code=0) Adding verbosity adds no additional information regarding the source/row/column that triggers this reaction. I have successfully executed "select * from <same-directory>" and that has run perfectly. For me this means that the issue is CTAS related. I'm running a fresh build from master to execute this. Any ideas/pointers? Regards, -Stefán
