-----------------------------------
Summary: compute_stats_long.q fails for wrong reasons
Key: HIVE-24672
URL: https://issues.apache.org/jira/browse/HIVE-24672
Project: Hive
Issue Type: Bug
Reporter: Mustafa İman
Assignee: Mustafa İman
TestNegativeCliDriver[compute_stats_long] intends to test fmsketch has a hard
limit on number of bit vectors (1024). However, the test fails for the
following wrong reason.
{code:java}
Caused by: java.lang.RuntimeException: Can not recognize 10000Caused by:
java.lang.RuntimeException: Can not recognize 10000 at
org.apache.hadoop.hive.common.ndv.NumDistinctValueEstimatorFactory.getEmptyNumDistinctValueEstimator(NumDistinctValueEstimatorFactory.java:71)
{code}
Instead it should fail with
{code:java}
Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: The maximum
allowed value for number of bit vectors is 1024, but was passed 10000 bit
vectorsCaused by: org.apache.hadoop.hive.ql.metadata.HiveException: The maximum
allowed value for number of bit vectors is 1024, but was passed 10000 bit
vectors at

~[hive-exec-4.0.0-SNAPSHOT.jar:4.0.0-SNAPSHOT]
{code}
Since this function is superseeded by compute_bit_vector_fm, it is best if we
add the same test for compute_bit_vector_fm too.
