Description

If assertion checking is enabled, ql/src/test/queries/clientpositive/dynamic_partition_pruning.q fails with an assertion failure in the following method of ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDFIn.java:

   public String getDisplayString(String[] children) {
    assert (children.length >= 2);

While dynamic_partition_pruning.q is running, getDisplayString() is called with children.length == 1.
