[jira] [Created] (HIVE-2752) Index names are case sensitive

Index names are case sensitive
------------------------------

                 Key: HIVE-2752
                 URL: https://issues.apache.org/jira/browse/HIVE-2752
             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)
	at org.apache.hadoop.hive.metastore.ObjectStore.alterIndex(ObjectStore.java:1880)
	at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler$30.run(HiveMetaStore.java:1930)
	at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler$30.run(HiveMetaStore.java:1927)

	at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.alter_index(HiveMetaStore.java:1927)
	at org.apache.hadoop.hive.metastore.HiveMetaStoreClient.alter_index(HiveMetaStoreClient.java:868)
	at org.apache.hadoop.hive.ql.metadata.Hive.alterIndex(Hive.java:398)
	at org.apache.hadoop.hive.ql.exec.DDLTask.alterIndex(DDLTask.java:902)
	at org.apache.hadoop.hive.ql.exec.DDLTask.execute(DDLTask.java:236)
	at org.apache.hadoop.hive.ql.exec.Task.executeTask(Task.java:134)
	at org.apache.hadoop.hive.ql.exec.TaskRunner.runSequential(TaskRunner.java:57)
	at org.apache.hadoop.hive.ql.Driver.launchTask(Driver.java:1332)
	at org.apache.hadoop.hive.ql.Driver.execute(Driver.java:1123)
	at org.apache.hadoop.hive.ql.Driver.run(Driver.java:931)
	at org.apache.hadoop.hive.cli.CliDriver.processLocalCmd(CliDriver.java:255)
	at org.apache.hadoop.hive.cli.CliDriver.processCmd(CliDriver.java:212)
	at org.apache.hadoop.hive.cli.CliDriver.processLine(CliDriver.java:403)
	at org.apache.hadoop.hive.cli.CliDriver.processLine(CliDriver.java:338)
	at org.apache.hadoop.hive.cli.CliDriver.processReader(CliDriver.java:436)
	at org.apache.hadoop.hive.cli.CliDriver.processFile(CliDriver.java:446)
	at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:642)
	at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:554)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
	at java.lang.reflect.Method.invoke(Method.java:597)
	at org.apache.hadoop.util.RunJar.main(RunJar.java:156)

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.

--------------------------------------

I can probably fix this, but I haven't really poked round the code. Feel free to assign to me.
