-----------------------------
Resolution: Not A Bug
> Exception
> :"org.apache.parquet.schema.IncompatibleSchemaModificationException: cannot
> merge original type
> ---------------------------------------------------------------------------------------------------------
>
> Key: PARQUET-1316
> URL: https://issues.apache.org/jira/browse/PARQUET-1316
> Project: Parquet
> Issue Type: Bug
> Reporter: Ashish
> Priority: Major
>
> I am merging large number(~5000) of tiny parq files into single bigger parq
> file using below command.
>
> java -jar <path to parquet-tools-1.9.1-SNAPSHOT.jar> merge <path to tiny parq
> files> <output file name>.
> *I am getting exception as
> "org.apache.parquet.schema.IncompatibleSchemaModificationException: cannot
> merge original type null into UTF8"*
>
> while searching for this exception I found that it is being generated from
> class 'GroupType.java' which is located in
> "parquet-mr-master/parquet-column/src/main/java/org/apache/parquet/schema"
> directory.
> I wanted to modify the code in this file and wanted to rebuild parq_tools
> using mvn clean package -Plocal command.
> *But the issue is mvn clean package -Plocal command is always downloading
> latest version of "parquet-column-1.9.1-SNAPSHOT.jar" in dir
> "/home/ubuntu/.m2/repository/org/apache/parquet/parquet-column/1.9.1-SNAPSHOT".*
> please suggest where shall I copy the compiled version of
> parquet-column-1.9.1-SNAPSHOT.jar , so that rebuliding of
> "parquet-tools-1.9.1-SNAPSHOT.jar" can take changes from my
> parquet-coumn-1.91.1-snapshot.jar file.
