Project: Hive
Issue Type: Bug
Components: Indexing, Metastore, Query Processor
Affects Versions: 0.9.0
Reporter: Philip Tromans
Priority: Minor
The following script:
DROP TABLE IF EXISTS TestTable;
CREATE TABLE TestTable (a INT);
DROP INDEX IF EXISTS TestTableA_IDX ON TestTable;
CREATE INDEX TestTableA_IDX ON TABLE TestTable (a) AS
'org.apache.hadoop.hive.ql.index.compact.CompactIndexHandler' WITH DEFERRED
REBUILD;
ALTER INDEX TestTableA_IDX ON TestTable REBUILD;
results in the following exception:
MetaException(message:index testtablea_idx doesn't exist)

When you execute: "SHOW INDEXES ON TestTable;", you get:
TestTableA_IDX testtable a
default__testtable_testtablea_idx__ compact
so it looks like things don't get lower cased when they go into the metastore,
but they do when the rebuild op is trying to execute.
