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

             Summary: schematool references wrong scripts directory
                 Key: HIVE-22268
                 URL: https://issues.apache.org/jira/browse/HIVE-22268
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 2.3.6, 3.1.2
            Reporter: Cameron Moberg


When running schematool on 2.3.6, 3.1.2 (no standalone metastore) and possibly others, the schematool uses a Java class org.apache.hadoop.hive.metastore.MetaStoreSchemaInfo where it checks for metastore script dirs `getMetaStoreScriptDir()`.

This function returns (essentially) scripts/*metastore*/upgrade/<FILE_NAME> whereas in 2.3.6 and 3.1.2 now it is *metastore/*scripts/upgrade/<FILE_NAME>.

 
{code:java}
// OLD
public String getMetaStoreScriptDir() {
    return  hiveHome + File.separatorChar +
        "scripts" + File.separatorChar + "metastore" +
	File.separatorChar + "upgrade" + File.separatorChar + dbType;
}

// NEW (tested only with schematool mysql)
public String getMetaStoreScriptDir() {
    return  hiveHome + File.separatorChar +
        "metastore" + File.separatorChar + "scripts" +
	File.separatorChar + "upgrade" + File.separatorChar + dbType;
}
{code}

I did test it by changing the code and swapping metastore/scripts in the method and it did work.
