[GitHub] [iceberg] edgarRd opened a new issue, #7122: Iceberg table in Hive fails with IndexOutOfBounds when BETWEEN filter used

edgarRd opened a new issue, #7122:
URL: https://github.com/apache/iceberg/issues/7122

   ### Apache Iceberg version
   
   1.1.0 (latest release)
   
   ### Query engine
   
   Hive
   
   ### Please describe the bug 🐞
   
   When using Hive `2.3.4` to read Iceberg tables, I've found cases where reads fail with:
   
   ```
   java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
     at java.util.ArrayList.rangeCheck(ArrayList.java:659)
     at java.util.ArrayList.get(ArrayList.java:435)
     at org.apache.iceberg.mr.hive.HiveIcebergFilterFactory.translateLeaf(HiveIcebergFilterFactory.java:111)
     at org.apache.iceberg.mr.hive.HiveIcebergFilterFactory.translate(HiveIcebergFilterFactory.java:82)
     at org.apache.iceberg.mr.hive.HiveIcebergFilterFactory.translate(HiveIcebergFilterFactory.java:76)
     at org.apache.iceberg.mr.hive.HiveIcebergFilterFactory.generateFilterExpression(HiveIcebergFilterFactory.java:53)
     at org.apache.iceberg.mr.hive.HiveIcebergInputFormat.getSplits(HiveIcebergInputFormat.java:90)
     at org.apache.hadoop.hive.ql.io.HiveInputFormat.addSplitsForGroup(HiveInputFormat.java:442)
     at org.apache.hadoop.hive.ql.io.HiveInputFormat.getSplits(HiveInputFormat.java:561)
     at org.apache.hadoop.hive.ql.exec.tez.HiveSplitGenerator.initialize(HiveSplitGenerator.java:196)
   ```
   
   My hypothesis is that Hive has run an optimization compacting leaves in the expression tree but the actual `tree` in the `SearchArguments` is not compacted to reflect this, leading to trying to access an index in the leaves that does not exist. This is possibly a bug in Hive (i.e. `tree` and `leaves` are not in-sync) but we can handle in Iceberg InputFormat by throwing `UnsupportedOperationException` avoiding the translation of the filter at all to pass down to Iceberg, the filter will later be applied by Hive, just like we handle other failure cases when converting `SearchArguments`.
