I saw new version of hadoop and orc-tools libraries, so I decided to update my project.

There are my new libraries:
implementation group: ‘org.apache.hadoop’, name: ‘hadoop-hdfs’, version: ‘3.4.0’
implementation(group: ‘org.apache.hadoop’, name: ‘hadoop-common’, version: ‘3.4.0’)
implementation(group: ‘org.apache.hive’, name: ‘hive-streaming’, version: ‘4.0.0’)
implementation(group: ‘org.apache.hadoop’, name: ‘hadoop-mapreduce-client-core’, version: ‘3.4.0’)
and orc-tools:
implementation ‘org.apache.orc:orc-tools:2.0.1’
and java 11->17

I want to use the method OrcFile.mergeFiles(…) but earch time a get Exception:

Caused by: java.lang.IllegalArgumentException: Incompatible merging of collection column statistics
at org.apache.orc.impl.ColumnStatisticsImpl$CollectionColumnStatisticsImpl.merge(ColumnStatisticsImpl.java:233)

I tried to merge three identical files(i had copied one file three times), but i got the same Exception.

Next my step was to merge this files using example from https://orc.apache.org/docs/java-tools.html:

java -jar orc-tools-2.0.1-uber.jar merge –output test.orc q/
And I got next Exception:
Exception in thread “main” java.lang.UnsatisfiedLinkError: ‘org.apache.hadoop.io.nativeio.NativeIO$POSIX$Stat org.apache.hadoop.io.nativeio.NativeIO$POSIX.stat(java.lang.String)’

I tried to invoke:

java -jar orc-tools-2.0.1-uber.jar count q/
And I got the same Exception.

Then I download orc-tools 1.9.4 and call:

java -jar orc-tools-1.9.4-uber.jar count q/

And I got result like:

file:/C:/work/1.orc 73338
file:/C:/work/2.orc 73338
file:/C:/work/3.orc 73338
file:/C:/work/4 73338
there were 4 identical files, so obtained number are OK.

Can somebody help me? What do i do wrong?
I want to merge a few orc files to one in java, but why orc-tools 2.0.1 doesn’t work too?
